Albert Einstein was a German mathematician and physicist who developed the special and general theories of relativity. In 1921, he won the Nobel Prize in Physics for his explanation of the photoelectric effect. In the following decade, he immigrated to the United States after being targeted by the German Nazi Party. His work also had a major impact on the development of atomic energy. In his later years, Einstein focused on unified field theory. He died in April 1955 at age 76. With his passion for inquiry, Einstein is generally considered the most influential physicist of the 20 th century.

FULL NAME: Albert Einstein BORN: March 14, 1879 DIED: April 18, 1955 BIRTHPLACE: Ulm, Württemberg, Germany SPOUSES: Mileva Einstein-Maric (1903-1919) and Elsa Einstein (1919-1936) CHILDREN: Lieserl, Hans, and Eduard ASTROLOGICAL SIGN: Pisces

Albert Einstein was born on March 14, 1879, in Ulm, Württemberg, Germany. He grew up in a secular Jewish family. His father, Hermann Einstein, was a salesman and engineer who, with his brother, founded Elektrotechnische Fabrik J. Einstein & Cie, a Munich-based company that mass-produced electrical equipment. Einstein’s mother, the former Pauline Koch, ran the family household. Einstein had one sister, Maja, born two years after him.

Einstein attended elementary school at the Luitpold Gymnasium in Munich. However, he felt alienated there and struggled with the institution’s rigid pedagogical style. He also had what were considered speech challenges. However, he developed a passion for classical music and playing the violin, which would stay with him into his later years. Most significantly, Einstein’s youth was marked by deep inquisitiveness and inquiry.

Toward the end of the 1880s, Max Talmud, a Polish medical student who sometimes dined with the Einstein family, became an informal tutor to young Einstein. Talmud had introduced his pupil to a children’s science text that inspired Einstein to dream about the nature of light. Thus, during his teens, Einstein penned what would be seen as his first major paper, “The Investigation of the State of Aether in Magnetic Fields.”

Hermann relocated the family to Milan, Italy, in the mid-1890s after his business lost out on a major contract. Einstein was left at a relative’s boarding house in Munich to complete his schooling at the Luitpold.

Faced with military duty when he turned of age, Einstein allegedly withdrew from classes, using a doctor’s note to excuse himself and claim nervous exhaustion. With their son rejoining them in Italy, his parents understood Einstein’s perspective but were concerned about his future prospects as a school dropout and draft dodger.

Einstein was eventually able to gain admission into the Swiss Federal Institute of Technology in Zurich, specifically due to his superb mathematics and physics scores on the entrance exam. He was still required to complete his pre-university education first and thus attended a high school in Aarau, Switzerland, helmed by Jost Winteler. Einstein lived with the schoolmaster’s family and fell in love with Winteler’s daughter Marie. Einstein later renounced his German citizenship and became a Swiss citizen at the dawn of the new century.

Einstein’s intelligence quotient was estimated to be around 160, but there are no indications he was ever actually tested.

Psychologist David Wechsler didn’t release the first edition of the WAIS cognitive test, which evolved into the WAIS-IV test commonly used today, until 1955—shortly before Einstein’s death. The maximum score of the current version is 160, with an IQ of 135 or higher ranking in the 99 th percentile.

Magazine columnist Marilyn vos Savant has the highest-ever recorded IQ at 228 and was featured in the Guinness Book of World Records in the late 1980s. However, Guinness discontinued the category because of debates about testing accuracy. According to Parade , individuals believed to have higher IQs than Einstein include Leonardo Da Vinci , Marie Curie , Nikola Tesla , and Nicolaus Copernicus .

After graduating from university, Einstein faced major challenges in terms of finding academic positions, having alienated some professors over not attending class more regularly in lieu of studying independently.

Einstein eventually found steady work in 1902 after receiving a referral for a clerk position in a Swiss patent office. While working at the patent office, Einstein had the time to further explore ideas that had taken hold during his university studies and thus cemented his theorems on what would be known as the principle of relativity.

In 1905—seen by many as a “miracle year” for the theorist—Einstein had four papers published in the Annalen der Physik , one of the best-known physics journals of the era. Two focused on the photoelectric effect and Brownian motion. The two others, which outlined E=MC 2 and the special theory of relativity, were defining for Einstein’s career and the course of the study of physics.

As a physicist, Einstein had many discoveries, but he is perhaps best known for his theory of relativity and the equation E=MC 2 , which foreshadowed the development of atomic power and the atomic bomb.

Theory of Relativity

Einstein first proposed a special theory of relativity in 1905 in his paper “On the Electrodynamics of Moving Bodies,” which took physics in an electrifying new direction. The theory explains that space and time are actually connected, and Einstein called this joint structure space-time.

By November 1915, Einstein completed the general theory of relativity, which accounted for gravity’s relationship to space-time. Einstein considered this theory the culmination of his life research. He was convinced of the merits of general relativity because it allowed for a more accurate prediction of planetary orbits around the sun, which fell short in Isaac Newton ’s theory. It also offered a more expansive, nuanced explanation of how gravitational forces worked.

Einstein’s assertions were affirmed via observations and measurements by British astronomers Sir Frank Dyson and Sir Arthur Eddington during the 1919 solar eclipse, and thus a global science icon was born. Today, the theories of relativity underpin the accuracy of GPS technology, among other phenomena.

Even so, Einstein did make one mistake when developing his general theory, which naturally predicted the universe is either expanding or contracting. Einstein didn’t believe this prediction initially, instead holding onto the belief that the universe was a fixed, static entity. To account for, this he factored in a “cosmological constant” to his equation. His later theories directly contracted this idea and asserted that the universe could be in a state of flux. Then, astronomer Edwin Hubble deduced that we indeed inhabit an expanding universe. Hubble and Einstein met at the Mount Wilson Observatory near Los Angeles in 1931.

Decades after Einstein’s death, in 2018, a team of scientists confirmed one aspect of Einstein’s general theory of relativity: that the light from a star passing close to a black hole would be stretched to longer wavelengths by the overwhelming gravitational field. Tracking star S2, their measurements indicated that the star’s orbital velocity increased to over 25 million kph as it neared the supermassive black hole at the center of the galaxy, its appearance shifting from blue to red as its wavelengths stretched to escape the pull of gravity.

Einstein’s E=MC²

Einstein’s 1905 paper on the matter-energy relationship proposed the equation E=MC²: the energy of a body (E) is equal to the mass (M) of that body times the speed of light squared (C²). This equation suggested that tiny particles of matter could be converted into huge amounts of energy, a discovery that heralded atomic power.

Famed quantum theorist Max Planck backed up the assertions of Einstein, who thus became a star of the lecture circuit and academia, taking on various positions before becoming director of the Kaiser Wilhelm Institute for Physics (today is known as the Max Planck Institute for Physics) from 1917 to 1933.

In 1921, Einstein won the Nobel Prize in Physics for his explanation of the photoelectric effect, since his ideas on relativity were still considered questionable. He wasn’t actually given the award until the following year due to a bureaucratic ruling, and during his acceptance speech, he still opted to speak about relativity.

Einstein married Mileva Maric on January 6, 1903. While attending school in Zurich, Einstein met Maric, a Serbian physics student. Einstein continued to grow closer to Maric, but his parents were strongly against the relationship due to her ethnic background.

Nonetheless, Einstein continued to see her, with the two developing a correspondence via letters in which he expressed many of his scientific ideas. Einstein’s father passed away in 1902, and the couple married shortly thereafter.

Einstein and Mavic had three children. Their daughter, Lieserl, was born in 1902 before their wedding and might have been later raised by Maric’s relatives or given up for adoption. Her ultimate fate and whereabouts remain a mystery. The couple also had two sons: Hans Albert Einstein, who became a well-known hydraulic engineer, and Eduard “Tete” Einstein, who was diagnosed with schizophrenia as a young man.

The Einsteins’ marriage would not be a happy one, with the two divorcing in 1919 and Maric having an emotional breakdown in connection to the split. Einstein, as part of a settlement, agreed to give Maric any funds he might receive from possibly winning the Nobel Prize in the future.

During his marriage to Maric, Einstein had also begun an affair some time earlier with a cousin, Elsa Löwenthal . The couple wed in 1919, the same year of Einstein’s divorce. He would continue to see other women throughout his second marriage, which ended with Löwenthal’s death in 1936.

In his 40s, Einstein traveled extensively and journaled about his experiences. Some of his unfiltered private thoughts are shared two volumes of The Travel Diaries of Albert Einstein .

The first volume , published in 2018, focuses on his five-and-a-half month trip to the Far East, Palestine, and Spain. The scientist started a sea journey to Japan in Marseille, France, in autumn of 1922, accompanied by his second wife, Elsa. They journeyed through the Suez Canal, then to Sri Lanka, Singapore, Hong Kong, Shanghai, and Japan. The couple returned to Germany via Palestine and Spain in March 1923.

The second volume , released in 2023, covers three months that he spent lecturing and traveling in Argentina, Uruguay, and Brazil in 1925.

The Travel Diaries contain unflattering analyses of the people he came across, including the Chinese, Sri Lankans, and Argentinians, a surprise coming from a man known for vehemently denouncing racism in his later years. In an entry for November 1922, Einstein refers to residents of Hong Kong as “industrious, filthy, lethargic people.”

In 1933, Einstein took on a position at the Institute for Advanced Study in Princeton, New Jersey, where he would spend the rest of his life.

At the time the Nazis, led by Adolf Hitler , were gaining prominence with violent propaganda and vitriol in an impoverished post-World War I Germany. The Nazi Party influenced other scientists to label Einstein’s work “Jewish physics.” Jewish citizens were barred from university work and other official jobs, and Einstein himself was targeted to be killed. Meanwhile, other European scientists also left regions threatened by Germany and immigrated to the United States, with concern over Nazi strategies to create an atomic weapon.

Not long after moving and beginning his career at IAS, Einstein expressed an appreciation for American meritocracy and the opportunities people had for free thought, a stark contrast to his own experiences coming of age. In 1935, Einstein was granted permanent residency in his adopted country and became an American citizen five years later.

In America, Einstein mostly devoted himself to working on a unified field theory, an all-embracing paradigm meant to unify the varied laws of physics. However, during World War II, he worked on Navy-based weapons systems and made big monetary donations to the military by auctioning off manuscripts worth millions.

In 1939, Einstein and fellow physicist Leo Szilard wrote to President Franklin D. Roosevelt to alert him of the possibility of a Nazi bomb and to galvanize the United States to create its own nuclear weapons.

The United States would eventually initiate the Manhattan Project , though Einstein wouldn’t take a direct part in its implementation due to his pacifist and socialist affiliations. Einstein was also the recipient of much scrutiny and major distrust from FBI director J. Edgar Hoover . In July 1940, the U.S. Army Intelligence office denied Einstein a security clearance to participate in the project, meaning J. Robert Oppenheimer and the scientists working in Los Alamos were forbidden from consulting with him.

Einstein had no knowledge of the U.S. plan to use atomic bombs in Japan in 1945. When he heard of the first bombing at Hiroshima, he reportedly said, “Ach! The world is not ready for it.”

Einstein became a major player in efforts to curtail usage of the A-bomb. The following year, he and Szilard founded the Emergency Committee of Atomic Scientists, and in 1947, via an essay for The Atlantic Monthly , Einstein espoused working with the United Nations to maintain nuclear weapons as a deterrent to conflict.

After World War II, Einstein continued to work on his unified field theory and key aspects of his general theory of relativity, including time travel, wormholes, black holes, and the origins of the universe.

However, he felt isolated in his endeavors since the majority of his colleagues had begun focusing their attention on quantum theory. In the last decade of his life, Einstein, who had always seen himself as a loner, withdrew even further from any sort of spotlight, preferring to stay close to Princeton and immerse himself in processing ideas with colleagues.

In the late 1940s, Einstein became a member of the National Association for the Advancement of Colored People (NAACP), seeing the parallels between the treatment of Jews in Germany and Black people in the United States. He corresponded with scholar and activist W.E.B. Du Bois as well as performer Paul Robeson and campaigned for civil rights, calling racism a “disease” in a 1946 Lincoln University speech.

Einstein was very particular about his sleep schedule, claiming he needed 10 hours of sleep per day to function well. His theory of relativity allegedly came to him in a dream about cows being electrocuted. He was also known to take regular naps. He is said to have held objects like a spoon or pencil in his hand while falling asleep. That way, he could wake up before hitting the second stage of sleep—a hypnagogic process believed to boost creativity and capture sleep-inspired ideas.

Although sleep was important to Einstein, socks were not. He was famous for refusing to wear them. According to a letter he wrote to future wife Elsa, he stopped wearing them because he was annoyed by his big toe pushing through the material and creating a hole.

albert einstein sticking out his tongue

One of the most recognizable photos of the 20 th century shows Einstein sticking out his tongue while leaving his 72 nd birthday party on March 14, 1951.

According to Discovery.com , Einstein was leaving his party at Princeton when a swarm of reporters and photographers approached and asked him to smile. Tired from doing so all night, he refused and rebelliously stuck his tongue out at the crowd for a moment before turning away. UPI photographer Arthur Sasse captured the shot.

Einstein was amused by the picture and ordered several prints to give to his friends. He also signed a copy of the photo that sold for $125,000 at a 2017 auction.

Einstein died on April 18, 1955, at age 76 at the University Medical Center at Princeton. The previous day, while working on a speech to honor Israel’s seventh anniversary, Einstein suffered an abdominal aortic aneurysm.

He was taken to the hospital for treatment but refused surgery, believing that he had lived his life and was content to accept his fate. “I want to go when I want,” he stated at the time. “It is tasteless to prolong life artificially. I have done my share, it is time to go. I will do it elegantly.”

According to the BBC, Einstein muttered a few words in German at the moment of his death. However, the nurse on duty didn’t speak German so their translation was lost forever.

In a 2014 interview , Life magazine photographer Ralph Morse said the hospital was swarmed by journalists, photographers, and onlookers once word of Einstein’s death spread. Morse decided to travel to Einstein’s office at the Institute for Advanced Studies, offering the superintendent alcohol to gain access. He was able to photograph the office just as Einstein left it.

After an autopsy, Einstein’s corpse was moved to a Princeton funeral home later that afternoon and then taken to Trenton, New Jersey, for a cremation ceremony. Morse said he was the only photographer present for the cremation, but Life managing editor Ed Thompson decided not to publish an exclusive story at the request of Einstein’s son Hans.

During Einstein’s autopsy, pathologist Thomas Stoltz Harvey had removed his brain, reportedly without his family’s consent, for preservation and future study by doctors of neuroscience.

However, during his life, Einstein participated in brain studies, and at least one biography claimed he hoped researchers would study his brain after he died. Einstein’s brain is now located at the Princeton University Medical Center. In keeping with his wishes, the rest of his body was cremated and the ashes scattered in a secret location.

In 1999, Canadian scientists who were studying Einstein’s brain found that his inferior parietal lobe, the area that processes spatial relationships, 3D-visualization, and mathematical thought, was 15 percent wider than in people who possess normal intelligence. According to The New York Times , the researchers believe it might help explain why Einstein was so intelligent.

In 2011, the Mütter Museum in Philadelphia received thin slices of Einstein’s brain from Dr. Lucy Rorke-Adams, a neuropathologist at the Children’s Hospital of Philadelphia, and put them on display. Rorke-Adams said she received the brain slides from Harvey.

Since Einstein’s death, a veritable mountain of books have been written on the iconic thinker’s life, including Einstein: His Life and Universe by Walter Isaacson and Einstein: A Biography by Jürgen Neffe, both from 2007. Einstein’s own words are presented in the collection The World As I See It .

Einstein has also been portrayed on screen. Michael Emil played a character called “The Professor,” clearly based on Einstein, in the 1985 film Insignificance —in which alternate versions of Einstein, Marilyn Monroe , Joe DiMaggio , and Joseph McCarthy cross paths in a New York City hotel.

Walter Matthau portrayed Einstein in the fictional 1994 comedy I.Q. , in which he plays matchmaker for his niece played by Meg Ryan . Einstein was also a character in the obscure comedy films I Killed Einstein, Gentlemen (1970) and Young Einstein (1988).

A much more historically accurate depiction of Einstein came in 2017, when he was the subject of the first season of Genius , a 10-part scripted miniseries by National Geographic. Johnny Flynn played a younger version of the scientist, while Geoffrey Rush portrayed Einstein in his later years after he had fled Germany. Ron Howard was the director.

Tom Conti plays Einstein in the 2023 biopic Oppenheimer , directed by Christopher Nolan and starring Cillian Murphy as scientist J. Robert Oppenheimer during his involvement with the Manhattan Project.

Albert Einstein Biography

Born: March 14, 1879 Ulm, Germany Died: April 18, 1955 Princeton, Massachusetts German-born American physicist and scientist

The German-born American physicist (one who studies matter and energy and the relationships between them) Albert Einstein revolutionized the science of physics. He is best known for his theory of relativity, which holds that measurements of space and time vary according to conditions such as the state of motion of the observer.

Early years and education

Albert Einstein was born on March 14, 1879, in Ulm, Germany, but he grew up and obtained his early education in Munich, Germany. He was a poor student, and some of his teachers thought he might be retarded (mentally handicapped); he was unable to speak fluently (with ease and grace) at age nine. Still, he was fascinated by the laws of nature, experiencing a deep feeling of wonder when puzzling over the invisible, yet real, force directing the needle of a compass. He began playing the violin at age six and would continue to play throughout his life. At age twelve he discovered geometry (the study of points, lines, and surfaces) and was taken by its clear and certain proofs. Einstein mastered calculus (a form of higher mathematics used to solve problems in physics and engineering) by age sixteen.

Einstein's formal secondary education ended at age sixteen. He disliked school, and just as he was planning to find a way to leave without hurting his chances for entering the university, his teacher expelled him because his bad attitude was affecting his classmates. Einstein tried to enter the Federal Institute of Technology (FIT) in Zurich, Switzerland, but his knowledge of subjects other than mathematics was not up to par, and he failed the entrance examination. On the advice of the principal, he first obtained his diploma at the Cantonal School in Aarau, Switzerland, and in 1896 he was automatically admitted into the FIT. There he came to realize that he was more interested in and better suited for physics than mathematics.

Einstein passed his examination to graduate from the FIT in 1900, but due to the opposition of one of his professors he was unable to go on to obtain the usual university assistantship. In 1902 he was hired as an inspector in the patent office in Bern, Switzerland. Six months later he married Mileva Maric, a former classmate in Zurich. They had two sons. It was in Bern, too, that Einstein, at twenty-six, completed the requirements for his doctoral degree and wrote the first of his revolutionary scientific papers.

Famous papers

Thermodynamics (the study of heat processes) made the deepest impression on Einstein. From 1902 until 1904 he reworked the foundations of thermodynamics and statistical mechanics (the study of forces and their effect on matter); this work formed the immediate background to his revolutionary papers of 1905, one of which was on Brownian motion.

In Brownian motion, first observed in 1827 by the Scottish botanist (scientist who studies plants) Robert Brown (1773–1858), small particles suspended in a liquid such as water undergo a rapid, irregular motion. Einstein, unaware of Brown's earlier observations, concluded from his studies that such a motion must exist. He was guided by the thought that if the liquid in which the particles are suspended is made up of atoms, they should collide with the particles and set them into motion. He found that the motion of the particles will in time experience a forward movement. Einstein proved that this forward movement is directly related to the number of atoms per gram of atomic weight. Brownian motion is to this day considered one of the most direct proofs of the existence of atoms.

The theory of relativity came from Einstein's search for a general law of nature that would explain a problem that had occurred to him when he was sixteen: if one runs at, say, 4 4 miles per hour (6.4 kilometers per hour) alongside a train that is moving at 4 4 miles per hour, the train appears to be at rest; if, on the other hand, it were possible to run alongside a ray of light, neither experiment nor theory suggests that the ray of light would appear to be at rest. Einstein realized that no matter what speed the observer is moving at, he must always observe the same velocity of light, which is roughly 186,000 miles per second (299,274 kilometers per second). He also saw that this was in agreement with a second assumption: if an observer at rest and an observer moving at constant speed carry out the same kind of experiment, they must get the same result. These two assumptions make up Einstein's special theory of relativity. Also in 1905 Einstein proved that his theory predicted that energy (E) and mass (m) are entirely related according to his famous equation, E=mc 2 . This means that the energy in any particle is equal to the particle's mass multiplied by the speed of light squared.

Academic career

These papers made Einstein famous, and universities soon began competing for his services. In 1909, after serving as a lecturer at the University of Bern, Einstein was called as an associate professor to the University of Zurich. Two years later he was appointed a full professor at the German University in Prague, Czechoslovakia. Within another year-and-a-half Einstein became a full professor at the FIT. Finally, in 1913 the well-known scientists Max Planck (1858–1947) and Walther Nernst (1864–1941) traveled to Zurich to persuade Einstein to accept a lucrative (profitable) research professorship at the University of Berlin in Germany, as well as full membership in the Prussian Academy of Science. He accepted their offer in 1914, saying, "The Germans are gambling on me as they would on a prize hen. I do not really know myself whether I shall ever really lay another egg." When he went to Berlin, his wife remained behind in Zurich with their two sons; they divorced, and Einstein married his cousin Elsa in 1917.

In 1920 Einstein was appointed to a lifelong honorary visiting professorship at the University of Leiden in Holland. In 1921 and 1922 Einstein, accompanied by Chaim Weizmann (1874–1952), the future president of the state of Israel, traveled all over the world to win support for the cause of Zionism (the establishing of an independent Jewish state). In Germany, where hatred of Jewish people was growing, the attacks on Einstein began. Philipp Lenard and Johannes Stark, both Nobel Prize–winning physicists, began referring to Einstein's theory of relativity as "Jewish physics." These kinds of attacks increased until Einstein resigned from the Prussian Academy of Science in 1933.

Career in America

On several occasions Einstein had visited the California Institute of Technology, and on his last trip to the United States he was offered a position in the newly established Institute for Advanced Studies in Princeton, Massachusetts. He went there in 1933.

Einstein played a key role (1939) in the construction of the atomic bomb by signing a famous letter to President Franklin D. Roosevelt (1882–1945). It said that the Germans had made scientific advances and that it was possible that Adolf Hitler (1889–1945, the German leader whose actions led to World War II [1939–45]), might become the first to have atomic weapons. This led to an all-out U.S. effort to construct such a bomb. Einstein was deeply shocked and saddened when his famous equation E=mc 2 was finally demonstrated in the most awesome and terrifying way by using the bomb to destroy Hiroshima, Japan, in 1945. For a long time he could only utter "Horrible, horrible."

It would be difficult to find a more suitable epitaph (a brief statement summing up a person's person's life) than the words Einstein himself used in describing his life: "God …gave me the stubbornness of a mule and nothing else; really …He also gave me a keen scent." On April 18, 1955, Einstein died in Princeton.

Einstein was born in Ulm, in the German state of Württemberg, on March 14, 1879, according to a biography from the Nobel Prize organization . His family moved to Munich six weeks later, and in 1885, when he was 6 years old, he began attending Petersschule, a Catholic elementary school.

Contrary to popular belief, Einstein was a good student. "Yesterday Albert received his grades, he was again number one, and his report card was brilliant," his mother once wrote to her sister, according to a German website dedicated to Einstein's legacy. But when he later switched to the Luitpold grammar school, young Einstein chafed under the school's authoritarian attitude, and his teacher once said of him, "never will he get anywhere."

In 1896, at age 17, Einstein entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. A few years later, he gained his diploma and acquired Swiss citizenship but was unable to find a teaching post. So he accepted a position as a technical assistant in the Swiss patent office.

Einstein married Mileva Maric, his longtime love and former student, in 1903. A year prior, they had a child out of wedlock, who was discovered by scholars only in the 1980s, when private letters revealed her existence. The daughter, called Lieserl in the letters, may have been mentally challenged and either died young or was adopted when she was a year old. Einstein had two other children with Maric, Hans Albert and Eduard, born in 1904 and 1910, respectively.

Einstein divorced Maric in 1919 and soon married his cousin Elsa Löwenthal, with whom he had been in a relationship since 1912.

Einstein obtained his doctorate in physics in 1905 — a year that's often known as his annus mirabilis ("year of miracles" in Latin), according to the Library of Congress . That year, he published four groundbreaking papers of significant importance in physics.

The first incorporated the idea that light could come in discrete particles called photons. This theory describes the photoelectric effect , the concept that underpins modern solar power. The second explained Brownian motion, or the random motion of particles or molecules. Einstein looked at the case of a dust mote moving randomly on the surface of water and suggested that water is made up of tiny, vibrating molecules that kick the dust back and forth. 

The final two papers outlined his theory of special relativity, which showed how observers moving at different speeds would agree about the speed of light, which was a constant. These papers also introduced the equation E = mc^2, showing the equivalence between mass and energy. That finding is perhaps the most widely known aspect of Einstein's work. (In this infamous equation, E stands for energy, m represents mass and c is the constant speed of light).

In 1915, Einstein published four papers outlining his theory of general relativity, which updated Isaac Newton's laws of gravity by explaining that the force of gravity arose because massive objects warp the fabric of space-time. The theory was validated in 1919, when British astronomer Arthur Eddington observed stars at the edge of the sun during a solar eclipse and was able to show that their light was bent by the sun's gravitational well, causing shifts in their perceived positions.

In 1921, he won the Nobel Prize in physics for his work on the photoelectric effect, though the committee members also mentioned his "services to Theoretical Physics" when presenting their award. The decision to give Einstein the award was controversial because the brilliant physicist was a Jew and a pacifist. Anti-Semitism was on the rise and relativity was not yet seen as a proven theory, according to an article from The Guardian .

Einstein was a professor at the University of Berlin for a time but fled Germany with Löwenthal in 1933, during the rise of Adolf Hitler. He renounced his German citizenship and moved to the United States to become a professor of theoretical physics at Princeton, becoming a U.S. citizen in 1940.

During this era, other researchers were creating a revolution by reformulating the rules of the smallest known entities in existence. The laws of quantum mechanics had been worked out by a group led by the Danish physicist Niels Bohr , and Einstein was intimately involved with their efforts.

Bohr and Einstein famously clashed over quantum mechanics. Bohr and his cohorts proposed that quantum particles behaved according to probabilistic laws, which Einstein found unacceptable, quipping that " God does not play dice with the universe ." Bohr's views eventually came to dominate much of contemporary thinking about quantum mechanics.

Einstein's later years and death

After he retired in 1945, Einstein spent most of his later years trying to unify gravity with electromagnetism in what's known as a unified field theory . Einstein died of a burst blood vessel near his heart on April 18, 1955, never unifying these forces.

Einstein's body was cremated and his ashes were spread in an undisclosed location, according to the American Museum of Natural History . But a doctor performed an unauthorized craniotomy before this and removed and saved Einstein's brain. 

The brain has been the subject of many tests over the decades, which suggested that it had extra folding in the gray matter, the site of conscious thinking. In particular, there were more folds in the frontal lobes, which have been tied to abstract thought and planning. However, drawing any conclusions about intelligence based on a single specimen is problematic.

In addition to his incredible legacy regarding relativity and quantum mechanics, Einstein conducted lesser-known research into a refrigeration method that required no motors, moving parts or coolant. He was also a tireless anti-war advocate, helping found the Bulletin of the Atomic Scientists , an organization dedicated to warning the public about the dangers of nuclear weapons . 

Einstein's theories concerning relativity have so far held up spectacularly as a predictive models. Astronomers have found that, as the legendary physicist anticipated, the light of distant objects is lensed by massive, closer entities, a phenomenon known as gravitational lensing, which has helped our understanding of the universe's evolution. The James Webb Space Telescope , launched in Dec. 2021, has utilized gravitational lensing on numerous occasions to detect light emitted near the dawn of time , dating to just a few hundred million years after the Big Bang.

In 2016, the Advanced Laser Interferometer Gravitational-Wave Observatory also announced the first-ever direct detection of gravitational waves , created when massive neutron stars and black holes merge and generate ripples in the fabric of space-time. Further research published in 2023 found that the entire universe may be rippling with a faint "gravitational wave background," emitted by ancient, colliding black holes.

Albert Einstein Biography

einstein

Einstein is also well known as an original free-thinker, speaking on a range of humanitarian and global issues. After contributing to the theoretical development of nuclear physics and encouraging F.D. Roosevelt to start the Manhattan Project, he later spoke out against the use of nuclear weapons.

Born in Germany to Jewish parents, Einstein settled in Switzerland and then, after Hitler’s rise to power, the United States. Einstein was a truly global man and one of the undisputed genius’ of the Twentieth Century.

Early life Albert Einstein

Einstein was born 14 March 1879, in Ulm the German Empire. His parents were working-class (salesman/engineer) and non-observant Jews. Aged 15, the family moved to Milan, Italy, where his father hoped Albert would become a mechanical engineer. However, despite Einstein’s intellect and thirst for knowledge, his early academic reports suggested anything but a glittering career in academia. His teachers found him dim and slow to learn. Part of the problem was that Albert expressed no interest in learning languages and the learning by rote that was popular at the time.

“School failed me, and I failed the school. It bored me. The teachers behaved like Feldwebel (sergeants). I wanted to learn what I wanted to know, but they wanted me to learn for the exam.” Einstein and the Poet (1983)

At the age of 12, Einstein picked up a book on geometry and read it cover to cover. – He would later refer to it as his ‘holy booklet’. He became fascinated by maths and taught himself – becoming acquainted with the great scientific discoveries of the age.

Despite Albert’s independent learning, he languished at school. Eventually, he was asked to leave by the authorities because his indifference was setting a bad example to other students.

He applied for admission to the Federal Institute of Technology in Zurich. His first attempt was a failure because he failed exams in botany, zoology and languages. However, he passed the next year and in 1900 became a Swiss citizen.

At college, he met a fellow student Mileva Maric, and after a long friendship, they married in 1903; they had two sons before divorcing several years later.

In 1896 Einstein renounced his German citizenship to avoid military conscription. For five years he was stateless, before successfully applying for Swiss citizenship in 1901. After graduating from Zurich college, he attempted to gain a teaching post but none was forthcoming; instead, he gained a job in the Swiss Patent Office.

While working at the Patent Office, Einstein continued his own scientific discoveries and began radical experiments to consider the nature of light and space.

Albert_Einstein_(Nobel)

Einstein in 1921

He published his first scientific paper in 1900, and by 1905 had completed his PhD entitled “ A New Determination of Molecular Dimensions . In addition to working on his PhD, Einstein also worked feverishly on other papers. In 1905, he published four pivotal scientific works, which would revolutionise modern physics. 1905 would later be referred to as his ‘ annus mirabilis .’

Einstein’s work started to gain recognition, and he was given a post at the University of Zurich (1909) and, in 1911, was offered the post of full-professor at the Charles-Ferdinand University in Prague (which was then part of Austria-Hungary Empire). He took Austrian-Hungary citizenship to accept the job. In 1914, he returned to Germany and was appointed a director of the Kaiser Wilhelm Institute for Physics. (1914–1932)

Albert Einstein’s Scientific Contributions

Quantum Theory

Einstein suggested that light doesn’t just travel as waves but as electric currents. This photoelectric effect could force metals to release a tiny stream of particles known as ‘quanta’. From this Quantum Theory, other inventors were able to develop devices such as television and movies. He was awarded the Nobel Prize in Physics in 1921.

Special Theory of Relativity

This theory was written in a simple style with no footnotes or academic references. The core of his theory of relativity is that:

“Movement can only be detected and measured as relative movement; the change of position of one body in respect to another.”

Thus there is no fixed absolute standard of comparison for judging the motion of the earth or plants. It was revolutionary because previously people had thought time and distance are absolutes. But, Einstein proved this not to be true.

He also said that if electrons travelled at close to the speed of light, their weight would increase.

This lead to Einstein’s famous equation:

Where E = energy m = mass and c = speed of light.

General Theory of Relativity 1916

Working from a basis of special relativity. Einstein sought to express all physical laws using equations based on mathematical equations.

He devoted the last period of his life trying to formulate a final unified field theory which included a rational explanation for electromagnetism. However, he was to be frustrated in searching for this final breakthrough theory.

Solar eclipse of 1919

In 1911, Einstein predicted the sun’s gravity would bend the light of another star. He based this on his new general theory of relativity. On 29 May 1919, during a solar eclipse, British astronomer and physicist Sir Arthur Eddington was able to confirm Einstein’s prediction. The news was published in newspapers around the world, and it made Einstein internationally known as a leading physicist. It was also symbolic of international co-operation between British and German scientists after the horrors of the First World War.

In the 1920s, Einstein travelled around the world – including the UK, US, Japan, Palestine and other countries. Einstein gave lectures to packed audiences and became an internationally recognised figure for his work on physics, but also his wider observations on world affairs.

Bohr-Einstein debates

During the 1920s, other scientists started developing the work of Einstein and coming to different conclusions on Quantum Physics. In 1925 and 1926, Einstein took part in debates with Max Born about the nature of relativity and quantum physics. Although the two disagreed on physics, they shared a mutual admiration.

As a German Jew, Einstein was threatened by the rise of the Nazi party. In 1933, when the Nazi’s seized power, they confiscated Einstein’s property, and later started burning his books. Einstein, then in England, took an offer to go to Princeton University in the US. He later wrote that he never had strong opinions about race and nationality but saw himself as a citizen of the world.

“I do not believe in race as such. Race is a fraud. All modern people are the conglomeration of so many ethnic mixtures that no pure race remains.”

Once in the US, Einstein dedicated himself to a strict discipline of academic study. He would spend no time on maintaining his dress and image. He considered these things ‘inessential’ and meant less time for his research. Einstein was notoriously absent-minded. In his youth, he once left his suitcase at a friends house. His friend’s parents told Einstein’s parents: “ That young man will never amount to anything, because he can’t remember anything.”

Although a bit of a loner, and happy in his own company, he had a good sense of humour. On January 3, 1943, Einstein received a letter from a girl who was having difficulties with mathematics in her studies. Einstein consoled her when he wrote in reply to her letter

“Do not worry about your difficulties in mathematics. I can assure you that mine are still greater.”

Einstein professed belief in a God “Who reveals himself in the harmony of all being”. But, he followed no established religion. His view of God sought to establish a harmony between science and religion.

“Science without religion is lame, religion without science is blind.”

– Einstein, Science and Religion (1941)

Politics of Einstein

Einstein described himself as a Zionist Socialist. He did support the state of Israel but became concerned about the narrow nationalism of the new state. In 1952, he was offered the position as President of Israel, but he declined saying he had:

“neither the natural ability nor the experience to deal with human beings.” … “I am deeply moved by the offer from our State of Israel, and at once saddened and ashamed that I cannot accept it.”

Citizen-Einstein

Einstein receiving US citizenship.

Albert Einstein was involved in many civil rights movements such as the American campaign to end lynching. He joined the National Association for the Advancement of Colored People (NAACP) and  considered racism, America’s worst disease. But he also spoke highly of the meritocracy in American society and the value of being able to speak freely.

On the outbreak of war in 1939, Einstein wrote to President Roosevelt about the prospect of Germany developing an atomic bomb. He warned Roosevelt that the Germans were working on a bomb with a devastating potential. Roosevelt headed his advice and started the Manhattan project to develop the US atom bomb. But, after the war ended, Einstein reverted to his pacifist views. Einstein said after the war.

“Had I known that the Germans would not succeed in producing an atomic bomb, I would not have lifted a finger.” (Newsweek, 10 March 1947)

In the post-war McCarthyite era, Einstein was scrutinised closely for potential Communist links. He wrote an article in favour of socialism, “Why Socialism” (1949) He criticised Capitalism and suggested a democratic socialist alternative. He was also a strong critic of the arms race. Einstein remarked:

“I do not know how the third World War will be fought, but I can tell you what they will use in the Fourth—rocks!”

Rabindranath_with_Einstein

Rabindranath Tagore and Einstein

Einstein was feted as a scientist, but he was a polymath with interests in many fields. In particular, he loved music. He wrote that if he had not been a scientist, he would have been a musician. Einstein played the violin to a high standard.

“I often think in music. I live my daydreams in music. I see my life in terms of music… I get most joy in life out of music.”

Einstein died in 1955, at his request his brain and vital organs were removed for scientific study.

Albert Einstein (March 14, 1879–April 18, 1955), a German-born theoretical physicist who lived during the 20th century, revolutionized scientific thought. Having developed the Theory of Relativity, Einstein opened the door for the development of atomic power and the creation of the atomic bomb.

Einstein is best known for his 1905 general theory of relativity, E=mc 2 , which posits that energy (E) equals mass (m) times the speed of light (c) squared. But his influence went far beyond that theory. Einstein's theories also changed thinking about how the planets revolve around the sun. For his scientific contributions, Einstein also won the 1921 Nobel Prize in physics.

Einstein also was forced to flee Nazi Germany after the rise of Adolf Hitler . It's no exaggeration to say that his theories indirectly helped lead the Allies to victory over the Axis powers in World War II, particularly the defeat of Japan.

Early Life and Education

Albert Einstein was born on March 14, 1879, in Ulm, Germany to Jewish parents, Hermann and Pauline Einstein. A year later, Hermann Einstein's business failed and he moved his family to Munich to start a new electric business with his brother Jakob. In Munich, Albert's sister Maja was born in 1881. Only two years apart in age, Albert adored his sister and they had a close relationship with each other their whole lives.

Although Einstein is now considered the epitome of genius, in the first two decades of his life, many people thought Einstein was the exact opposite. Right after Einstein was born, relatives were concerned with Einstein's pointy head. Then, when Einstein didn't talk until he was 3 years old, his parents worried something was wrong with him.

Einstein also failed to impress his teachers. From elementary school through college, his teachers and professors thought he was lazy, sloppy, and insubordinate. Many of his teachers thought he would never amount to anything.

When Einstein was 15 years old, his father's new business had failed and the Einstein family moved to Italy. At first, Albert remained behind in Germany to finish high school, but he was soon unhappy with that arrangement and left school to rejoin his family.

Rather than finish high school, Einstein decided to apply directly to the prestigious Polytechnic Institute in Zurich, Switzerland. Although he failed the entrance exam on the first try, he spent a year studying at a local high school and retook the entrance exam in October 1896 and passed.

Once at the Polytechnic, Einstein again did not like school. Believing that his professors only taught old science, Einstein would often skip class, preferring to stay home and read about the newest in scientific theory. When he did attend class, Einstein would often make it obvious that he found the class dull.

Some last-minute studying allowed Einstein to graduate in 1900. However, once out of school, Einstein was unable to find a job because none of his teachers liked him enough to write him a recommendation letter.

For nearly two years, Einstein worked at short-term jobs until a friend was able to help him get a job as a patent clerk at the Swiss Patent Office in Bern. Finally, with a job and some stability, Einstein was able to marry his college sweetheart, Mileva Maric, whom his parents strongly disapproved.

The couple went on to have two sons: Hans Albert (born 1904) and Eduard (born 1910).

Einstein the Patent Clerk

For seven years, Einstein worked six days a week as a patent clerk. He was responsible for examining the blueprints of other people's inventions and then determining whether they were feasible. If they were, Einstein had to ensure that no one else had already been given a patent for the same idea.

Somehow, between his very busy work and family life, Einstein not only found time to earn a doctorate from the University of Zurich (awarded 1905) but found time to think. It was while working at the patent office that Einstein made his most influential discoveries.

Influential Theories

In 1905, while working at the patent office, Einstein wrote five scientific papers, which were all published in the Annalen der Physik ( Annals of Physics , a major physics journal). Three of these were published together in September 1905.

In one paper, Einstein theorized that light must not just travel in waves but existed as particles, which explained the photoelectric effect. Einstein himself described this particular theory as "revolutionary." This was also the theory for which Einstein won the Nobel Prize in Physics in 1921.

In another paper, Einstein tackled the mystery of why pollen never settled to the bottom of a glass of water but rather, kept moving (Brownian motion). By declaring that the pollen was being moved by water molecules, Einstein solved a longstanding, scientific mystery and proved the existence of molecules.

His third paper described Einstein's "Special Theory of Relativity," in which Einstein revealed that space and time are not absolutes. The only thing that is constant, Einstein stated, is the speed of light; the rest of space and time are all based on the position of the observer.

Not only are space and time not absolutes, Einstein discovered that energy and mass, once thought completely distinct items, were actually interchangeable. In his E=mc 2  equation (E=energy, m=mass, and c=speed of light), Einstein created a simple formula to describe the relationship between energy and mass. This formula reveals that a very small amount of mass can be converted into a huge amount of energy, leading to the later invention of the atomic bomb.

Einstein was only 26 years old when these articles were published and already he had done more for science than any individual since Sir Isaac Newton.

Scientists Take Notice

In 1909, four years after his theories were first published, Einstein was finally offered a teaching position. Einstein enjoyed being a teacher at the University of Zurich. He had found traditional schooling as he grew up extremely limiting and thus he wanted to be a different kind of teacher. Arriving at school unkempt, with hair uncombed and his clothes too baggy, Einstein soon became known as much for his appearance as his teaching style.

As Einstein's fame within the scientific community grew, offers for new, better positions began to pour in. Within only a few years, Einstein worked at the University of Zurich ( Switzerland ), then the German University in Prague (Czech Republic), and then went back to Zurich for the Polytechnic Institute.

The frequent moves, the numerous conferences that Einstein attended, and preoccupation of Einstein with science left Mileva (Einstein's wife) feeling both neglected and lonely. When Einstein was offered a professorship at the University of Berlin in 1913, she didn't want to go. Einstein accepted the position anyway.

Not long after arriving in Berlin, Mileva and Albert separated. Realizing the marriage could not be salvaged, Mileva took the kids back to Zurich. They officially divorced in 1919.

Achieves Worldwide Fame

During  World War I , Einstein stayed in Berlin and worked diligently on new theories. He worked like a man obsessed. With Mileva gone, he often forgot to eat and sleep.

In 1917, the stress eventually took its toll and he collapsed. Diagnosed with gallstones, Einstein was told to rest. During his recuperation, Einstein's cousin Elsa helped nurse him back to health. The two became very close and when Albert's divorce was finalized, Albert and Elsa married.

It was during this time that Einstein revealed his General Theory of Relativity, which considered the effects of acceleration and gravity on time and space. If Einstein's theory was correct, then the gravity of the sun would bend light from stars.

In 1919, Einstein's General Theory of Relativity could be tested during a solar eclipse. In May 1919, two British astronomers (Arthur Eddington and Sir Frances Dyson) were able to put together an expedition that observed the  solar eclipse  and documented the bent light. In November 1919, their findings were announced publicly.

After having suffered monumental bloodshed during World War I, people around the world were craving news that went beyond their country's borders. Einstein became a worldwide celebrity overnight.

It wasn't just his revolutionary theories; it was Einstein's general persona that appealed to the masses. Einstein's disheveled hair, poorly fitting clothes, doe-like eyes, and witty charm endeared him to the average person. He was a genius, but he was an approachable one.

Instantly famous, Einstein was hounded by reporters and photographers wherever he went. He was given honorary degrees and asked to visit countries around the world. Albert and Elsa took trips to the United States, Japan, Palestine (now Israel), South America, and throughout Europe.

Becomes an Enemy of the State

Although Einstein spent the 1920s traveling and making special appearances, these took away from the time he could work on his scientific theories. By the early 1930s, finding time for science wasn't his only problem.

The political climate in Germany was changing drastically. When Adolf Hitler took power in 1933, Einstein was luckily visiting the United States (he never returned to Germany). The Nazis promptly declared Einstein an enemy of the state, ransacked his house, and burned his books.

As death threats began, Einstein finalized his plans to take a position at the Institute for Advanced Study at Princeton, New Jersey. He arrived at Princeton on Oct. 17, 1933.

Einstein suffered a personal loss when Elsa died on Dec. 20, 1936. Three years later, Einstein's sister Maja fled from  Mussolini's Italy and came to live with Einstein in Princeton. She stayed until her death in 1951.

Until the Nazis took power in Germany, Einstein had been a devoted pacifist for his entire life. However, with the harrowing tales coming out of Nazi-occupied Europe, Einstein reevaluated his pacifist ideals. In the case of the Nazis, Einstein realized they needed to be stopped, even if that meant using military might to do so.

The Atomic Bomb

In July 1939, scientists Leo Szilard and Eugene Wigner visited Einstein to discuss the possibility that Germany was working on building an atomic bomb.

The ramifications of Germany building such a destructive weapon prompted Einstein to write a letter to  President Franklin D. Roosevelt  to warn him about this potentially massive weapon. In response, Roosevelt established the  Manhattan Project , a collection of U.S. scientists urged to beat Germany to the construction of a working atomic bomb.

Even though Einstein's letter prompted the Manhattan Project, Einstein himself never worked on constructing the atomic bomb.

Later Years and Death

From 1922 until the end of his life, Einstein worked on finding a "unified field theory." Believing that "God does not play dice," Einstein searched for a single, unified theory that could combine all the fundamental forces of physics between elementary particles. Einstein never found it.

In the years after World War II , Einstein advocated for a world government and for civil rights. In 1952, after the death of Israel's first President Chaim Weizmann , Einstein was offered the presidency of Israel. Realizing that he was not good at politics and too aged to start something new, Einstein declined the offer.

On April 12, 1955, Einstein collapsed at his home. Just six days later, on April 18, 1955, Einstein died when the aneurysm he had been living with for several years finally burst. He was 76 years old.

Albert Einstein The Nobel Prize in Physics 1921

Born: 14 March 1879, Ulm, Germany

Died: 18 April 1955, Princeton, NJ, USA

Affiliation at the time of the award: Kaiser-Wilhelm-Institut (now Max-Planck-Institut) für Physik, Berlin, Germany

Prize motivation: “for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect”

Albert Einstein received his Nobel Prize one year later, in 1922.

Prize share: 1/1

Albert Einstein grew up in Munich, where his father founded an electrical engineering company. After studying at the ETH university in Zurich, Einstein worked at the patent office in Bern, during which time he produced several pioneering works in the field of physics. He was later employed at universities in Bern, Zurich, and Prague, and from 1914, in Berlin. After the Nazis seized power in Germany, Einstein immigrated to the US, where he worked at the Institute for Advanced Study in Princeton, New Jersey. Einstein married twice and had three children by his first marriage.

If metal electrodes are exposed to light, electrical sparks between them occur more readily. For this photoelectric effect to occur, the light waves must be above a certain frequency, however. According to physics theory, the light's intensity should be critical. In one of several epoch-making studies beginning in 1905, Albert Einstein explained that light consists of quanta—packets with fixed energies corresponding to certain frequencies. One such light quantum, a photon, must have a certain minimum frequency before it can liberate an electron.

Albert Einstein

The embodiment of genius and the pre-eminent scientist of the modern age, his theories and discoveries have profoundly affected the way people view and understand the world and their place in it. Einstein was also known as a philosopher and humanist who was keenly interested in and concerned about the affairs of the world.

His sagacious, wise, and humorous quotations, letters, and articles are widely used throughout popular culture as well as in historical and academic works. Einstein’s name and image are instantly recognizable everywhere in the world.

Albert Einstein was a theoretical physicist and the most famous scientist in human history. He developed the general theory of relativity, one of the two pillars of modern physics, alongside quantum mechanics. He is perhaps best known in popular culture for his mass/energy equivalence formula E=mc2. In 1921 he received the Nobel Prize in Physics for his “services to theoretical physics”, and in particular his discovery of the photoelectric effect, a pivotal step in the evolution of quantum theory.

Einstein was born in Ulm, Germany on March 14, 1879. As a child, he exhibited an extraordinary curiosity for and understanding of the mysteries of science. The young Einstein also took music lessons, playing both violin and piano; stoking a passion for music that he maintained throughout his life. Moving first to Italy and then Switzerland, the young prodigy graduated from high school in 1896.

In 1905, while working as a patent clerk in Bern, Switzerland, Einstein had what came to be known as his “Annus Mirabilis” (miracle year). It was during this time that the young physicist obtained his Doctorate degree and published four of his most influential research papers, including the Special Theory of Relativity, the Photoelectric Effect, Brownian Motion, and Mass/Energy Equivalence, and his worldwide fame was assured. In 1915, Einstein completed his General Theory of Relativity, and brought to the world a fuller understanding of the interaction of space, time and gravity.

The practical applications of Einstein’s theories include the development of everyday and indispensable items such as Televisions, Remote Controls, Digital Cameras, and GPS tracking systems.

In 1999 Albert Einstein was recognized by TIME Magazine as the “Person of the Century”. Einstein’s intellect, along with his wise and passionate dedication to the causes of social justice and pacifism, left humanity with a fuller understanding of its place in the universe and with pioneering moral guidance for future generations.

Albert Einstein (1879 - 1955)

Albert Einstein

Albert Einstein was born at Ulm in Baden-Wurttemberg, Germany, on March 14, 1879, into a non-observant Jewish family. At age five, his father showed him a pocket compass, and Einstein realized that something in "empty" space acted upon the needle; he would later describe the experience as one of the most revelatory of his life.

Although considered a slow learner, possibly due to dyslexia, simply shyness or the significantly rare and unusual structure his brain (examined after his death), Einstein built models and mechanical devices for fun. Another, more recent, theory about his mental development is that he had Asperger's syndrome, a condition related to autism.

Einstein began to learn mathematics around age 12. In 1894, his family moved from Munich to Pavia, Italy (near Milan), and this same year Einstein wrote his first scientific work, The Investigation of the State of Aether in Magnetic Fields. He continued his education at Aarau, Switzerland, and in 1896, he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, he gained his diploma and acquired Swiss citizenship. Unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office, obtaining his doctor's degree in 1905.

In 1908, Einstein was appointed Privadozent in Berne. The next year, he became Professor Extraordinary in Zurich, and in 1911 Professor of Theoretical Physics at Prague, returning to Zurich in 1912 to fill a similar post. In 1914, he was appointed Director of the Kaiser Wilhelm Physical Institute and Professor in the University of Berlin. He became a German citizen in 1914 and remained in Berlin until 1933, when he renounced his citizenship for political reasons and emigrated to America to take the position of Professor of Theoretical Physics at Princeton. He became a U.S. citizen in 1940 and retired from his post in 1945.

In his early days in Berlin, Einstein postulated that they correct interpretation of the special theory of relativity must also furnish a theory of gravitation, and in 1916 he published his paper on the general theory of relativity. During this time, he also contributed to the problems of the theory of radiation and statistical mechanics. In the 1920s, he embarked on the construction of unified field theories, continuing to work on the probabilistic interpretation of quantum theory, and he persevered with this work in America. He won a Nobel Prize for Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." He contributed to statistical mechanics by his development of the quantum theory of a monatomic gas, and he has also accomplished valuable work in connection with atomic transition probabilities and relativistic cosmology.

Einstein initially favored construction of the atomic bomb, in order to ensure that Hitler did not do so first, and even sent a letter, dated August 2, 1939, to President Roosevelt encouraging him to initiate a program to create a nuclear weapon. Roosevelt responded to this by setting up a committee for the investigation of using uranium as a weapon, which in a few years was superseded by the Manhattan Project.

After the war, however, Einstein lobbied for nuclear disarmament and a world government. Along with Albert Schweitzer and Bertrand Russell, he fought against nuclear tests and bombs. As his last public act, and just days before his death, he signed the Russell-Einstein Manifesto, which led to the Pugwash Conferences on Science and World Affairs.

Einstein's latter years were also spent searching for a unified field theory, for a universal force that would link gravitation with electromagnetic and subatomic forces, a problem on which no one to date has been entirely successful.

Einstein received honorary doctorate degrees in science, medicine and philosophy from many European and American universities. During the 1920s, he lectured in Europe, America and the Far East and was awarded Fellowships or Memberships to all of the leading scientific academies throughout the world. He gained numerous awards in recognition of his work, including the Copley Medal of the Royal Society of London in 1925, and the Franklin Medal of the Franklin Institute in 1935.

Einstein married Mileva Maric in 1903, and they had a daughter and two sons; the marriage was dissolved in 1919, and that same year he married his cousin Elsa Lowenthal, who died in 1936. Einstein died on April 18, 1955, in Princeton, New Jersey. Element 99 was named einsteinium (Es) in his honor.

Albert Einstein Biography – The Journey From Clerk To The Greatest Physicist

long biography of albert einstein

Share This Article

Sed ut perspiciatis unde.

Albert Einstein passed away on April 18, 1955, at the age of 76 years. He was the most influential physicist of all time. To remember him adequately, well talk about his life in this article, from just a little boy & clerk to the time he changed physics as we know it and his eventual death.

Young Roots

Albert Einstein, son of Hermann Einstein (His father), a salesman and engineer, and Pauline Einstein (His mother), was born on March 14th in Ulm, Germany. Not long after his birth, his family moved to Munich, where young Albert Einstein, learned how to play the violin and the piano (due to his mother’s background). Music was so important to him he once said “If I were not a physicist, I would be a musician. I often think in music, I live my daydreams in music, I see my life in terms of music… I get the most joy in life out of music”.

Albert Einstein spent his teenage years in Munich, having decent grades, but by no means outstanding. He did have, however, remarkable success in mathematics. He enjoyed it so much his father got him a tutor to teach him. In less than a year, though, “his genius was so high I could not follow” , as was later said by the tutor. It’s thought that by the age of 14 Albert Einstein had already mastered integral and differential calculus.

Italy and University

His devotion to the sciences was noted in his admission tests at the Swiss Federal Polytechnic, in Zurich, Switzerland (his family had moved to Milan, Italy, a city relatively close to Zurich, due to financial problems).

He had the highest grades in math and physics but failed in everything else. He spent the following year learning his lacking knowledge in these disciplines, under the guard of Jost Winteler , a professor at the University, and his family. During this year he also met with his first love, Marie Winteler (his professor’s daughter), and renounce German citizenship, to skip compulsory military training.

In the next year, he passed his university exams, although barely passing in Greek and Latin. Here he meets his future first wife, Mileva Maric , the only girl in his class, and one of its top students. Also, in university Einstein rarely frequented classes, preferring to learn the subjects alone in his room. This caused his teachers to alienate him, and it made it very difficult for Einstein to find a job as a professor when he got out of University.

Miracle Year

Due to this difficulty caused by his teachers he went on working as a clerk in the Swiss Patent Office for Intellectual Property in 1901. It was common for Einstein to work on physics, such as writing his thesis for his doctorate, while working at the desk.

In 1905 he finished his thesis and received his PhD. from the Zurich University . During this year he also published 4 articles. The subjects of each article were –

  • Photoelectric effect (He would later receive a Nobel Prize in 1921 for this)
  • Brownian motion
  • Special Relativity
  • Equivalence of mass and energy (In this article/research paper, he would first write E=mc 2 , which laid the groundwork for nuclear physics)

It was the 4 th article that made him famous, and he was recognized by Max Planck , known as the father of quantum physics, as a pioneer. From this point on Einstein started receiving dozens of lecture requests, along with teaching positions. During the following years, he worked at various places, such as Austria, Zurich, his alma mater, and Berlin, staying in Berlin from 1914 to 1933.

  • The Sad Story of Former ISRO Scientist – Nambi Narayanan

Time in Berlin

During his time in Berlin, though, lots of things happened. Einstein started an extra-marital relationship with his first cousin, Elsa Lowenthal , which would result in family problems with his current wife, Mileva. Albert Einstein wasn’t already a family man (he rarely spent time with any of his 3 kids, or his wife, for that matter) and these problems culminated in their divorce in 1919. In the same year, Einstein married his cousin, Elsa.

The year 1919 brought even more news though. Einstein’s general relativity (This theory explained that gravity between masses results from their warping of space-time ), which Einstein finished in 1916, proved this year during a solar eclipse. You see, according to GR, the light would also be affected by gravity (because of E=mc 2 ), meaning you would be able to see objects that were behind the sun, during a solar eclipse. Two years later he received a Nobel Prize for the photoelectric effect because GR and SR weren’t still completely recognized by the scientific community.

In 1933, when Hitler won the elections in Germany, Albert Einstein went to the USA, bringing along the way a thousand new scientists, to avoid their persecution by the Nazis.

USA and WWII

In the USA, Albert Einstein was appointed as professor of physics at Princeton University , one of the most regarded schools in the world. Here Einstein worked on finding a way to conciliate GR with quantum mechanics, creating a theory of everything, but his quest reached a dead end.

In 1939 he was key for the creation of Project Manhattan, which resulted in the creation of atomic bombs. When two small scientists found what they thought could be a way of constructing an atomic bomb, Albert Einstein signed a petition to call President Roosevelt’s attention. Einstein wasn’t appointed for the project because of public opinion (he was German you see).

In his last months, Albert Einstein deeply regrets this action, saying “I made one great mistake in my life (…) when I signed the letter to President Roosevelt recommending that atom bombs be made.”

Last moments

Einstein eventually passed away in 1955 due to a kidney problem. When the option of operation was recommended, he said “I want to go when I want (…) I have done my share; It’s time to go. I’ll do it elegantly”.   His last words aren’t known , because they were in German, and the nurse that was present at the time was American.

Edward walter maunder (12 apr 1851 - 21 mar 1928).

He was an English astronomer who first started the British Civil Services Commission examination for the post of photographic and spectroscopic assistant at the Royal Observatory, Greenwich. He worked at the observatory for the next forty years measuring the sunspots and checking historic records. He found a lack of reports on sunspots from 1645 to 1715. Instead of questioning this, he started researching and found that there are indeed decades-long times when the sun has very few sunspots. Now we call these periods as Maunder minima.

Ferdinand von Lindemann (12 Apr 1852 - 6 Mar 1939)

He was a German mathematician who proved that π is not a solution to any algebraic equation with a rational coefficient. This explained the insoluble natural or classical Greek mathematical problem of constructing a square with the same area as a given circle using a ruler and compasses alone. He discussed Hermite’s methods that he used to prove that ‘e’ is transcendental. He extended Hermite’s results in 1882 to show that π was also transcendental.

Charles messier (26 jun 1730 - 12 apr 1817).

He was a French astronomer who first compiled a systematic catalog of “M objects” and discovered 15 comets. His catalog contained nebulae, 103-star clusters, and galaxies. He concluded the alphanumeric names for objects like M1, M2, etc.

Geoffrey F. Chew (5 Jun 1924 - 12 Apr 2019)

He was an American physicist who led the group of S-matrix theorists researching the strong interaction and the bootstrap principle. He was a graduate student of Enrico Fermi . His group calculated the interactions of bound-states without assuming that there is a point-particle field theory underneath.

Igor Tamm (8 Jul 1895 - 12 Apr 1971)

He was a Soviet physicist who shared the Noble Prize with Pavel A  Cherenkov , and Ilya M. Frank for physics for his works in explaining Cherenkov radiation . He developed the theoretical interpretation of the Cherenkov effect which states that the radiation of electrons moves faster than the speed of light through matter. He also developed a method for studying the interaction of nuclear particles and contributed towards the methods for the control of thermonuclear reactions.

First man to orbit the earth.

On this day, Yuri Gagarin became the first man to orbit the Earth in 1961. The control of the spacecraft was locked to prevent him from taking control of the ship. It had a radio, television, and life-supporting equipment. He ejected and made a planned descent landing with his parachute but the Soviet Union denied this to save its reputation. After 7 years, he died in a plane crash.

9 Things You May Not Know About Albert Einstein

By: Evan Andrews

Updated: August 29, 2018 | Original: October 26, 2015

long biography of albert einstein

1. Einstein didn’t fail math as a child.

albert einstein

Underachieving school kids have long taken solace in the claim that Einstein flunked math as a youth, but the records show that he was actually an exceptional, if not reluctant, student. He scored high grades during his school days in Munich, and was only frustrated by what he described as the “mechanical discipline” demanded by his teachers. The future Nobel Laureate dropped out of school at age 15 and left Germany to avoid state-mandated military service, but before then he was consistently at the top of his class and was even considered something of a prodigy for his grasp of complex mathematical and scientific concepts. When later presented with a news article claiming he’d failed grade-school math, Einstein dismissed the story as a myth and said, “Before I was 15 I had mastered differential and integral calculus.”

2. No one knows what happened to his first daughter.

In 1896, Einstein renounced his German citizenship and enrolled at the Swiss Federal Polytechnic School in Zurich. There, he began a passionate love affair with Mileva Maric, a fellow physicist-in-training originally from Serbia. The couple later married and had two sons after graduating, but a year before they tied the knot, Maric gave birth to an illegitimate daughter named Lieserl. Einstein never spoke about the child to his family, and biographers weren’t even aware of her existence until examining his private papers in the late-1980s. Her fate remains a mystery to this day. Some scholars think Lieserl died from scarlet fever in 1903, while others believe she survived the sickness and was given up for adoption in Maric’s native Serbia.

3. It took Einstein nine years to get a job in academia.

Einstein showed flashes of brilliance during his years at the Zurich Polytechnic, but his rebellious personality and penchant for skipping classes saw his professors give him less than glowing recommendations upon his graduation in 1900. The young physicist later spent two years searching for an academic position before settling for a gig at the Swiss patent office in Bern. Though menial, the job turned out to be a perfect fit for Einstein, who found he could breeze through his office duties in a few hours and spend the rest of the day writing and conducting research. In 1905—often called his “miracle year”—the lowly clerk published four revolutionary articles that introduced his famous equation E=mc2 and the theory of special relativity. While the discoveries marked Einstein’s entrance onto the physics world stage, he didn’t win a full professorship until 1909—nearly a decade after he had left school.

4. He offered his wife his Nobel Prize as part of their divorce settlement.

After his marriage to Mileva Maric hit the rocks in the early 1910s, Einstein left his family, moved to Berlin and started a new relationship with his cousin, Elsa. He and Maric finally divorced several years later in 1919. As part of their separation agreement, Einstein promised her an annual stipend plus whatever money he might receive from the Nobel Prize—which he was supremely confident he would eventually win. Maric agreed, and Einstein later handed over a small fortune upon receiving the award in 1922 for his work on the photoelectric effect. By then, he had already remarried to Elsa, who remained his wife until her death in 1936.

5. A solar eclipse helped make Einstein world famous.

In 1915, Einstein published his theory of general relativity, which stated that gravitational fields cause distortions in the fabric of space and time. Because it was such a bold rewriting of the laws of physics, the theory remained controversial until May 1919, when a total solar eclipse provided the proper conditions to test its claim that a supermassive object—in this case the sun—would cause a measurable curve in the starlight passing by it. Hoping to prove Einstein’s theory once and for all, English astronomer Arthur Eddington journeyed to the coast of West Africa and photographed the eclipse. Upon analyzing the pictures, he confirmed that the sun’s gravity had deflected the light by roughly 1.7 arc-seconds—exactly as predicted by general relativity. The news made Einstein an overnight celebrity. Newspapers hailed him as the heir to Sir Isaac Newton, and he went on to travel the world lecturing on his theories about the cosmos. According to Einstein biographer Walter Isaacson, in the six years after the 1919 eclipse, more than 600 books and articles were written about the theory of relativity.

6. The FBI spied on him for decades.

Shortly before Hitler rose to power in 1933, Einstein left Berlin for the United States and took a position at the Institute for Advanced Study in Princeton, New Jersey. His support for pacifist, civil rights and left-wing causes had already drawn suspicion from J. Edgar Hoover’s FBI, and after his arrival on American shores, the Bureau launched what would eventually become a 22-year surveillance campaign. Agents listened to the physicist’s phone calls, opened his mail and rooted through his trash in the hope of unmasking him as a subversive or a Soviet spy. They even investigated tips that he was building a death ray. The project came up empty handed, but by the time Einstein died in 1955, his FBI file totaled a whopping 1,800 pages.

7. Einstein urged the building of the atomic bomb—and later became a proponent of nuclear disarmament.

In the late-1930s, Einstein learned that new research had put German scientists on a path toward creating the atom bomb. The prospect of a doomsday weapon in the hands of the Nazis convinced him to set aside his pacifist principles and team up with Hungarian physicist Leo Szilard, who helped him write a letter urging President Franklin D. Roosevelt to conduct atomic research. Though Einstein never participated directly in the Manhattan Project, he later expressed deep regrets about his minor role in bringing about the Hiroshima and Nagasaki bombings. “Had I known that the Germans would not succeed in producing an atomic bomb, I never would have lifted a finger,” he told Newsweek. He went on to become an impassioned advocate of nuclear disarmament, controls on weapons testing and unified world government. Shortly before his death in 1955, he joined with philosopher Bertrand Russell in signing the “Russell-Einstein Manifesto,” a public letter that stressed the risks of nuclear war and implored governments to “find peaceful means for the settlement of all disputes between them.”

8. He was asked to be president of Israel.

a;bert einstein

Though not traditionally religious, Einstein felt a deep connection to his Jewish heritage and often spoke out against anti-Semitism. He was never a staunch Zionist, but when head of state Chaim Weizmann died in 1952, the Israeli government offered to appoint him as the nation’s second president. The 73-year-old wasted little time in declining the honor. “All my life I have dealt with objective matters,” Einstein wrote in a letter to the Israeli ambassador, “hence I lack both the natural aptitude and the experience to deal properly with people and to exercise official function.”

9. Einstein’s brain was stolen after his death.

Einstein died in April 1955 from an abdominal aortic aneurysm. He had requested that his body be cremated, but in a bizarre incident, Princeton pathologist Thomas Harvey removed his famous brain during his autopsy and kept it in the hope of unlocking the secrets of his genius. After winning a reluctant approval from Einstein’s son, Harvey later had the brain cut into pieces and sent to various scientists for research. A handful of studies have been conduced on it since the 1980s, but most have either been dismissed or discredited. Perhaps the most famous came in 1999, when a team from a Canadian university published a controversial paper claiming Einstein possessed unusual folds on his parietal lobe, a part of the brain associated with mathematical and spatial ability.

Albert Einstein is arguably one of the most influential individuals in the modern world. He played a role in the development and physics, and also dabbled with the politics of his day-even though at a small scale level. During the period around the First World War, Einstein was among the individuals that were against the usage of violence in resolution of conflicts. This was one of the ethical standpoints that have made him receive credence, years after his death.

Albert Einstein was born in Württemberg, Germany, on March 14, 1879 (Meltzer 2). Less than two months after his birth his family relocated to Munich where he started his education. As years passed by, Einstein and his family again relocated, this time to Switzerland, where the young Albert gained a diploma in physics and mathematics (Lakin 20). After his graduation, Einstein tried to find a job as a teacher but instead landed a position in Switzerland’s patent office (Frisch 12).

In 1905, at just 26, Einstein received a doctoral degree. It was during this period that he published most his remarkable theories. By 1911 he had been declared Professor Extraordinary and Professor of Theoretical Physics in different cities across Switzerland (Frisch 23). Einstein was fundamentally a pacifist when it came to conflict resolution and this was well manifested in the First World War.

During this time, 93 German professors supported a manifesto for the conduct of the nation in war, while Einstein and three other intellectuals gave their support to an anti-war counter manifesto (Calaprice and Lipscombe 121).

Einstein played a critical role in the establishment of a non-partisan coalition that fronted the idea of just piece and international cooperation in the prevention of wars in the future. During his stay in Switzerland, Einstein spent his days as a theoretical physicist but also dedicated some time to uniting the warring factions. He even once declared his stand thus:

“My pacifism is an instinctive feeling, a feeling that possesses me because the murder of men is disgusting. My attitude is not derived from any intellectual theory but is based on my deepest antipathy to every kind of cruelty and hatred ” (Calaprice and Lipscombe 55.)

In 1914, he moved back to Germany where he stayed as a citizen for the next nineteen years, only to renounce his citizenship on political grounds. He moved the United States where he stayed for seven years before acquiring American Citizenship. In the meantime, he continued teaching Theoretical Physics at Princeton University.

After the Second World War, Albert Einstein was a key official in the World Government Movement. He was even accorded the presidency of Israel but he turned down the offer instead choosing to spearhead the establishment of the Hebrew University of Jerusalem.

When it came to science, Einstein had a proper knowledge of the challenges in the field and also had a well developed way of dealing with them. His was a methodological approach with clear-cut steps towards the attainment of the goal. According to Einstein, any of his achievements was merely seen as a stepping stone to even more achievements.

In his early professional years, Albert Einstein hypothesized that the right explanation of the special theory of relativity should also inform the theory of gravitation (McPherson 21). In 1916 he published his paper on the general theory of relativity (McPherson 26). It was around this period that he took time to find solutions to the challenges of the theory of radiation. In the 1920’s, Einstein started working on the unified field theories but still continued his work on the quantum theory (Calaprice and Lipscombe 92). By the time he was retiring, Einstein had made substantial achievements in relativistic cosmology and unification of basic concepts of Physics.

Owing to his accomplishments, Einstein was awarded several honorary doctorate degrees in various scientific fields by many European and American universities (Lakin 33-35). A number of prestigious societies also accorded him awards, most notably the Copley Medal of the Royal Society of London in 1925 (Lakin 43). Because of his involvement in research, Einstein spent a lot of time in solitude and his only form of recreation was listening to music. In 1903, he got married and had two children before filing for a divorce sixteen years later only to marry his cousin, Elsa Löwenthal, who passed away in 1936 (Meachen 13). Einstein died in New Jersey, 19 years after Elsa’s death

Einstein’s theories survived the test of time primarily because of two reasons. One, because most of his work was based on the findings of scholars that became before him, and two because the field in which he was involved had no room for more advancement without scholars taking his findings into consideration.

His ethical views regarding the war have long been overshadowed by the entry of other more popular individuals, most of them being politicians. As a pacifist, his political views did not initially find popularity with the rulers of his time because most of them believed in national supremacy. As a matter of fact, most individuals dismissed his and his associate’s viewpoints as the ranting of mad scientists.

Various life lessons can be picked from how Einstein conducted himself. First is the commitment to one’s job. Most individuals always complain of how bad their current job is without even making an effort to attain their best in what they do. For instance, with the global boundaries becoming more and more irrelevant owing to increasing international migration, the United States is gradually becoming multicultural. Individuals from all over the world have over time appreciated the United States as the land of opportunity.

Hence, most persons ranging from professionals to unskilled individuals are looking for ways to gain an entry into America where they earnings are thought to be better than in other regions around the world.

The search for jobs and better livelihoods has resulted in an increased diversification of the American workforce which in turn calls for institutions to adopt and develop strategies for strengthening the relationship between individuals of varied socio-cultural backgrounds. What most individuals fail to notice, is that if they commit themselves to what they are good at, they can end up making notable achievements in their lives.

Another ethical lesson that can be picked from Einstein’s life is his belief in peaceful resolution of national and international conflicts. This is something that Einstein directly linked to leadership whereby leadership is the definite role assigned to each and every president/country.

The most common and wrong presumption by most presidents is that since their job title puts them in a position of leadership, the individuals who work under them will automatically be subject to their every word. In actual sense, however, the title presidency is not necessarily directly linked to leadership.

Einstein believed in proper communication among communities as a way of reaching amicable solutions to disagreements. Community communication is the practice of sharing information amongst individual of a given society. Communication has always been hailed as one of the key unifiers of members of particular communities. The easier it is for individuals to share what is in their minds, the easier it is for them to relate with one another.

Communication as a social aspect is multi faceted in the sense that it comprises various different aspects working both independently and in conjunction with other components to maintain a harmonious understanding between parties. In most societies around the world business is regarded as the mainstay. All activities within a given community generally tend to be under the influence of economic activities both directly and indirectly.

In order for effectiveness to be achieved in leadership, the person in charge must constantly ensure that his/her influence to the people subordinate to him/her is always positive and intended to achieve the unique goals of the country. Furthermore, and in line with Einstein’s beliefs, it has been proven that the leadership style adopted can make people in governmental control either excellent or terrible leaders. In this regard, if the leaders of two nations are pacifiers, then there is a reduced likelihood of international wars.

Another trait that made Einstein a great person was his belief in giving everyone a chance to be heard. Good listenership has been given immense appreciation amongst the most successful communities in the world. The doctrines of these societies propose that for anyone to have a meaningful conversation and particularly in business, he or she must be in a position to take time and listen to what the other person is saying. It is quite unlikely that communication can occur if both of the parties involved talk at the same time.

Communication is a two way event that calls for one of the parties to stay quite and receive the message and then respond as the other party stays quiet. At national levels, if all the leaders sit down and agree to communicate sanely, then there is little likelihood of disagreements occurring on account of misunderstanding.

Einstein’s persona and ethical beliefs redefined the meaning of the word school as a place where people spend time with an aim of becoming more knowledgeable. According to him, it is in schools that students are exposed to basic political values particularly of their country as well as going through extensive studies of how political systems operate.

As a result, the students are able to come up with independent opinions regarding politics and the political elites. This is fundamentally the root of conservatism which has a number of assumptions. One of these sensible assumptions is the imperfection of the human nature. This is because human beings are inherently selfish and will generally be driven to act in ways that are only beneficial to them.

Human imperfection also reveals in the corruptible nature of persons. Another sensible assumption of conservatism, and which was also reflected in Einstein’s persona, is the belief that people basically get their individual identity from their nation and family.

This is practically true because the learning process demands that persons learn from the people closest to them as well as from their country of habitation. The traditionalism ideology based on the fact that institutions which have existed for long periods of time have most credibility also makes a lot of sense. This is a self-explanatory concept especially since it is well known that experience makes the best teacher.

Einstein also put strong emphasis on respect of the rule of law by citizens. This is a very sensible conservative assumption as it is by individuals observing established regulations and trusting the various arms of government to implement such regulations that stability can be obtained now and in the future.
