Albert Einstein

By: History.com Editors

Updated: May 16, 2019 | Original: October 27, 2009

The German-born physicist Albert Einstein developed the first of his groundbreaking theories while working as a clerk in the Swiss patent office in Bern. After making his name with four scientific articles published in 1905, he went on to win worldwide fame for his general theory of relativity and a Nobel Prize in 1921 for his explanation of the phenomenon known as the photoelectric effect. An outspoken pacifist who was publicly identified with the Zionist movement, Einstein emigrated from Germany to the United States when the Nazis took power before World War II. He lived and worked in Princeton, New Jersey, for the remainder of his life.

Einstein’s Early Life (1879-1904)

Born on March 14, 1879, in the southern German city of Ulm, Albert Einstein grew up in a middle-class Jewish family in Munich. As a child, Einstein became fascinated by music (he played the violin), mathematics and science. He dropped out of school in 1894 and moved to Switzerland, where he resumed his schooling and later gained admission to the Swiss Federal Polytechnic Institute in Zurich. In 1896, he renounced his German citizenship, and remained officially stateless before becoming a Swiss citizen in 1901.

Did you know? Almost immediately after Albert Einstein learned of the atomic bomb's use in Japan, he became an advocate for nuclear disarmament. He formed the Emergency Committee of Atomic Scientists and backed Manhattan Project scientist J. Robert Oppenheimer in his opposition to the hydrogen bomb.

While at Zurich Polytechnic, Einstein fell in love with his fellow student Mileva Maric, but his parents opposed the match and he lacked the money to marry. The couple had an illegitimate daughter, Lieserl, born in early 1902, of whom little is known. After finding a position as a clerk at the Swiss patent office in Bern, Einstein married Maric in 1903; they would have two more children, Hans Albert (born 1904) and Eduard (born 1910).

Einstein’s Miracle Year (1905)

While working at the patent office, Einstein did some of the most creative work of his life, producing no fewer than four groundbreaking articles in 1905 alone. In the first paper, he applied the quantum theory (developed by German physicist Max Planck) to light in order to explain the phenomenon known as the photoelectric effect, by which a material will emit electrically charged particles when hit by light. The second article contained Einstein’s experimental proof of the existence of atoms, which he got by analyzing the phenomenon of Brownian motion, in which tiny particles were suspended in water.

In the third and most famous article, titled “On the Electrodynamics of Moving Bodies,” Einstein confronted the apparent contradiction between two principal theories of physics: Isaac Newton’s concepts of absolute space and time and James Clerk Maxwell’s idea that the speed of light was a constant. To do this, Einstein introduced his special theory of relativity, which held that the laws of physics are the same even for objects moving in different inertial frames (i.e. at constant speeds relative to each other), and that the speed of light is a constant in all inertial frames. A fourth paper concerned the fundamental relationship between mass and energy, concepts viewed previously as completely separate. Einstein’s famous equation E = mc2 (where “c” was the constant speed of light) expressed this relationship.

From Zurich to Berlin (1906-1932)

Einstein continued working at the patent office until 1909, when he finally found a full-time academic post at the University of Zurich. In 1913, he arrived at the University of Berlin, where he was made director of the Kaiser Wilhelm Institute for Physics. The move coincided with the beginning of Einstein’s romantic relationship with a cousin of his, Elsa Lowenthal, whom he would eventually marry after divorcing Mileva. In 1915, Einstein published the general theory of relativity, which he considered his masterwork. This theory found that gravity, as well as motion, can affect time and space. According to Einstein’s equivalence principle–which held that gravity’s pull in one direction is equivalent to an acceleration of speed in the opposite direction–if light is bent by acceleration, it must also be bent by gravity. In 1919, two expeditions sent to perform experiments during a solar eclipse found that light rays from distant stars were deflected or bent by the gravity of the sun in just the way Einstein had predicted.

The general theory of relativity was the first major theory of gravity since Newton’s, more than 250 years before, and the results made a tremendous splash worldwide, with the London Times proclaiming a “Revolution in Science” and a “New Theory of the Universe.” Einstein began touring the world, speaking in front of crowds of thousands in the United States, Britain, France and Japan. In 1921, he won the Nobel Prize for his work on the photoelectric effect, as his work on relativity remained controversial at the time. Einstein soon began building on his theories to form a new science of cosmology, which held that the universe was dynamic instead of static, and was capable of expanding and contracting.

Einstein Moves to the United States (1933-39)

A longtime pacifist and a Jew, Einstein became the target of hostility in Weimar Germany, where many citizens were suffering plummeting economic fortunes in the aftermath of defeat in the Great War. In December 1932, a month before Adolf Hitler became chancellor of Germany, Einstein made the decision to emigrate to the United States, where he took a position at the newly founded Institute for Advanced Study in Princeton, New Jersey . He would never again enter the country of his birth.

By the time Einstein’s wife Elsa died in 1936, he had been involved for more than a decade with his efforts to find a unified field theory, which would incorporate all the laws of the universe, and those of physics, into a single framework. In the process, Einstein became increasingly isolated from many of his colleagues, who were focused mainly on the quantum theory and its implications, rather than on relativity.

Einstein’s Later Life (1939-1955)

In the late 1930s, Einstein’s theories, including his equation E=mc2, helped form the basis of the development of the atomic bomb. In 1939, at the urging of the Hungarian physicist Leo Szilard, Einstein wrote to President Franklin D. Roosevelt advising him to approve funding for the development of uranium before Germany could gain the upper hand. Einstein, who became a U.S. citizen in 1940 but retained his Swiss citizenship, was never asked to participate in the resulting Manhattan Project , as the U.S. government suspected his socialist and pacifist views. In 1952, Einstein declined an offer extended by David Ben-Gurion, Israel’s premier, to become president of Israel .

Throughout the last years of his life, Einstein continued his quest for a unified field theory. Though he published an article on the theory in Scientific American in 1950, it remained unfinished when he died, of an aortic aneurysm, five years later. In the decades following his death, Einstein’s reputation and stature in the world of physics only grew, as physicists began to unravel the mystery of the so-called “strong force” (the missing piece of his unified field theory) and space satellites further verified the principles of his cosmology.

Albert Einstein

In November 1915, Albert Einstein published his theory of gravitation, thus attaining international renown which was to last unfailingly until the present day, long after his death. The history of his general theory of relativity, however, took a different course. It lost its appeal in the 1920s and did not experience a resurgence until the mid-1950s. Researchers at the Max Planck Institute for the History of Science have traced this surprising development.

Albert Einstein Biography

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.

Albert Einstein with wife Elsa

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.

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.”

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 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 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.

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.

• My passionate interest in social justice and social responsibility has always stood in curious contrast to a marked lack of desire for direct association with men and women. I am a horse for single harness, not cut out for tandem or team work. I have never belonged wholeheartedly to country or state, to my circle of friends, or even to my own family.

32 fun and random facts about Albert Einstein

Albert Einstein was much more than a scientific genius. From his political beliefs to his hatred of socks, here are 32 facts about Einstein you might not have heard before.

Albert Einstein was arguably the most famous scientist of the 20th century. Most people are familiar with his iconic E=mc^2 equation , but his life and work encompassed so much more than that. For instance, the brilliant physicist actually won the Nobel Prize for very different work. From his humble beginnings as a patent clerk to the offer to run a small country (that he turned down), here are 32 facts you may not have known about Einstein.

Einstein discovered that the universe has a "speed limit." 

His special theory of relativity, which explains the relationship between mass, time and space, suggests that as an object approaches the speed of light, its mass and energy become infinite, as Space.com explains . That means that it's impossible for an object to travel faster than light.

He argued that space and time are interwoven. 

While Einstein didn't invent the concept of space-time, which was first proposed by German mathematician Hermann Minkowski , his special theory of relativity showed that space and time grow and shrink relative to one another in order to keep the speed of light constant for the observer. Based on his theory , when we travel through space, time moves a tiny bit slower. At incredible speeds, like the speed of light, time stands still.

He won the Nobel Prize for his explanation of the photoelectric effect. 

The photoelectric effect is the observation that metal plates eject electrons when hit by beams of high-energy light. The photoelectric effect can't be explained by classical physics, which saw light as a wave. Einstein proposed that we view light as both a particle and a wave — with the frequency of the wave determining the energy of the particle and vice versa. 

Einstein transformed the way physicists view light.

Before Einstein's special theory of relativity, physicists thought that light traveled through a substance called "the luminiferous ether." Throughout the late 19th century, scientists ran experiments to try to prove its existence.

Einstein's fascination with physics was lifelong.

Beginning at age 5, Einstein became captivated by the invisible forces that moved the needle of his compass, according to the American Physical Society . That led to a lifelong quest to explain those invisible forces.

At the age of 12, he taught himself geometry. 

To study, he read out of a textbook, which he dubbed his " holy geometry book " and "second miracle" (the first being his compass needle).

He wasn't well-liked by his teachers.

One of the instructors at the Luitpold-Gymnasium in Munich, where Einstein received much of his early education, told the young Einstein that nothing good would ever come of his life. 

Einstein played the violin.

At 5 years old, his mother signed him up for lessons. At first, he didn't enjoy playing at all, according to the American Nuclear Society . But after discovering Mozart, he developed a love for the hobby and played into his old age.

He wrote his first scientific paper at the age of 16.

Titled " On the Investigation of the State of the Ether in a Magnetic Field ," the essay asked how magnetic fields impact " ether ," the theoretical substance that at the time was believed to transmit electromagnetic waves. 

After university, Einstein was rejected from every academic position he applied for.

Eventually, he settled for a job evaluating patent claims for the Swiss government, according to the American Institute of Physics . He described the job, which gave him the time and energy to focus on solving the physics problems that underlie our world, as "a kind of salvation."

He helped convince the physics world that atoms exist. 

Einstein was interested in the problem of Brownian motion , the observation that if you put tiny objects (like pollen) in water, they appear to jump around erratically. Einstein proposed that invisible particles were colliding with the pollen, causing it to move, and came up with a formula describing this phenomenon. In 1908, French physicist Jean Baptiste Perrin tested and confirmed Einstein's theory, swaying the physics world to accept the existence of atoms, according to the American Physical Society . 

Einstein was a pacifist.

At 16, he left Germany to escape mandatory military service. Later, he was one of only four German intellectuals to openly declare their opposition to German participation in World War I, calling nationalism " the measles of the human race ." 

Einstein's theories of relativity challenged the view that the universe was static.

His equations predicted a dynamic universe, one that was expanding or contracting. Flummoxed by this finding, Einstein assumed there was a flaw in his equations and introduced a " cosmological constant " which allowed for a universe that didn't change size. When Edwin Hubble confirmed that the universe is, indeed, expanding, Einstein called the cosmological constant "his greatest mistake."

Four of Einstein's most notable papers were all published in one year. 

In 1905, dubbed his " year of miracles ," Einstein published his explanation of the photoelectric effect, his theory on Brownian motion, and two papers on his general theory of relativity. 

He was friends with Charlie Chaplin.

Chaplin even invited Einstein and his wife , Elsa Einstein, as his guests of honor at the premier of his 1931 film "City Lights." There, Chaplin famously told Einstein : "The people applaud me because everybody understands me, and they applaud you because no one understands you."

Einstein believed in God.

However, he didn't believe in a personal god that answered prayers. Instead, he thought that God revealed himself through the "harmony" of the universe. "He [God] does not play dice," he famously wrote . 

Einstein was a target for the Nazis.

They sponsored conferences and book burnings against Einstein and labeled his theories " Jewish physics ." In 1933, Einstein fled Germany to escape Nazi death threats, settling first in Britain and then eventually in Princeton, New Jersey.

His work enabled the development of the atomic bomb.

The equation E = mc2 provided the theoretical basis for the weapon's potential — but didn't explain how to build one. 

At the start of World War II, he wrote to then-President Franklin D. Roosevelt, warning of possible German nuclear weapons research.

He urged the president to initiate development of an atomic bomb — but later regretted doing so, according to the American History of Natural History . In an interview with Newsweek, he said: "Had I known that the Germans would not succeed in developing an atomic bomb, I would have done nothing."

Later, he opposed the use of atomic weapons. 

After the bombing of Hiroshima and Nagasaki, he formed the Emergency Committee of Atomic Scientists , an organization that educated Americans about the dangers of atomic weapons.

Einstein was a member of the National Association for the Advancement of Colored People (NAACP). 

He saw parallels between the experience of Black Americans and his experience as a Jew living in Nazi Germany. In a 1946 commencement speech delivered at the historically black college Lincoln University, Einstein decried segregation and called it "a disease of white people," Smithsonian magazine reported.

The FBI kept a 1,400-page dossier on Einstein.

His pacifist stance and left-leaning politics made him suspicious in the eyes of the agency as a potentially "extreme radical," National Geographic reported. This was especially true during the McCarthy era, when many people were accused of communism or blacklisted from work. 

Einstein was asked to be the president of Israel. 

However, when he was offered the position in 1952, he was already near the end of his life, according to the American Museum of Natural History . Due to his poor health and lack of experience "dealing properly with people," he declined.

He did not believe that black holes could exist. 

In a 1939 article, he laid out a series of arguments trying to prove that black holes — objects with such high gravity that even light can't escape them — are impossible, Scientific American reported . Ironically, It's Einstein's general theory of relativity that shows us black holes do, in fact, exist. 

He did believe in the possibility of wormholes.

In a 1935 paper published in the journal Physics Reviews , Einstein and physicist Nathan Rosen proposed that near objects of enormous mass, space-time might curve inward like a rubber tube, creating a tunnel between two different regions. If they exist, these objects would enable travel across vast distances of time and space, Space.com reported.

Einstein didn't wear socks. 

Black holes weren't the only holes this physicist vehemently disagreed with. Because socks invariably develop holes, he disliked them to such an extent that he refused to wear them, according to the American Nuclear Society .

Einstein's brain was stolen.

After his death in 1955, pathologist Thomas Harvey dissected and stole Einstein's brain during an autopsy. Harvey, who wanted to discover the anatomical secrets of genius, eventually received permission from Einstein's son to use the brain for scientific research.

Research on Einstein's brain found extra folding. 

The human brain's wrinkled surface gives it a much larger surface area than a smooth brain and is an important part of advanced cognition. Einstein's brain had extra folding in its gray matter, the site of conscious thinking, especially in the frontal lobe, where abstract thought and planning occurs.

He loved sailing. 

However, the physicist was terrible at it — so terrible, in fact, that his neighbors frequently had to rescue him when is boat invariably capsized, according to the American Nuclear Society .

His birthday is Pi Day. 

March 14 is a special date because written numerically, it matches the first three digits of mathematical constant pi: 3.14. However, that's not the only reason it's significant. It's also the birthday of Einstein , who was born in 1879.

Einstein invented a refrigerator. 

The contraption, which he developed alongside colleague Leo Szilard, didn't require motors or coolant. Instead, it used boiling butane to suck energy from a compartment, lowering the temperature inside, Live Science previously reported.

Einstein's ultimate goal was to describe the workings of the entire universe — from subatomic particles to the farthest reaches of space — in one theory. 

He called the concept " The Grand Unified Theory ." He never realized this dream, but physicists are still working to find it.

“The radio has to fulfil a special and unique function for international reconciliation.”

Albert Einstein, 1930

SOUND DOCUMENT OF ALBERT EINSTEIN

On August 22 in 1930 Albert Einstein held a speech on the exhibition site at the radio tower in Berlin-Charlottenburg at the opening of the 7. Deutsche Funkausstellung und Phonoschau (7th German Radio and Audio Show) in Berlin. The speech which was broadcast via radio was held at stormy weather and near the trams rattling along in the open. Both these unfavourable circumstances and the technical imperfection of the back then sound recording are reflected in the sound quality which can be listened to here.

Despite the shortness of the sound document Einstein’s simple way of lecturing can be recognized. It is pepped up with little jokes. His slightly south German dialect can be heard well, too. Einstein received vivid applause at the end of his speech.

Original text of Einstein’s speech

Those parts in the sound document which are marked blue can be listened to ( in German ).

“Ladies and Gentlemen who are present and who are not!

When you hear the radio think also about the fact how people have come to possess such a wonderful tool of communication. The origin of all technical achievements is the divine curiosity and the play instinct of the working and thinking researcher as well as the constructive fantasy of the technical inventor.

Think of Oersted who as the first person noticed the magnetic effect of electric currents, of Reis who as the first one made use of this effect to generate sound by using electromagnetism, of Bell who as the first person converted sound waves into variable electric currents with his microphone by using sensitive contacts. Think also of Maxwell who showed us the existence of electric waves by using a mathematical way, of Hertz who as the first person generated them with the help of a spark and thus proved them. Think especially of Liebens who invented an unprecedented measuring instrument for electric pulses, the electric valve tube. It was also an ideal and simple instrument to generate electric waves. Think gratefully of the big number of unknown engineers who simplified the instruments of communication via radio and adapted them to mass production in such a fashion that they have become ready to be used by everybody nowadays.

And everybody should be ashamed who uses the wonders of science and engineering without thinking and having mentally realized not more of it than a cow realizes of the botany of the plants which it eats with pleasure.

Think also about the fact that it is the engineers who make true democracy possible. They facilitate not only the daily work of the people but also make the works of the finest thinkers and artists accessible to the public. The pleasure of these works had recently still been a privilege of the preferred classes. Thus the engineers wake the peoples from their sleepy bluntness.

The radio has to fulfil a special and unique function for international reconciliation. Up to now peoples got to know each other almost only with the help of the distorting mirror of their own daily press. Radio shows them to each other in their most vivid form and mainly from their amicable side. Thus it will contribute to end the feeling of bilateral strangeness which so easily turns to mistrust and hostility.

With this attitude look at the results of the creation which this exhibition offers the astonished senses of the visitors.”

Original text of Einstein’s speech in German:

“Verehrte An- und Abwesende!

Wenn Ihr den Rundfunk höret, so denkt auch daran, wie die Menschen in den Besitz dieses wunderbaren Werkzeuges der Mitteilung gekommen sind. Der Urquell aller technischen Errungenschaften ist die göttliche Neugier und der Spieltrieb des bastelnden und grübelnden Forschers und nicht minder die konstruktive Phantasie des technischen Erfinders.

Denkt an Oersted, der zuerst die magnetische Wirkung elektrischer Ströme bemerkte, an Reis, der diese Wirkung zuerst benutzte, um auf elektromagnetischem Wege Schall zu erzeugen, an Bell, der unter Benutzung empfindlicher Kontakte mit seinem Mikrophon zuerst Schallschwingungen in variable elektrische Ströme verwandelte. Denkt auch an Maxwell, der die Existenz elektrischer Wellen auf mathematischem Wege aufzeigte, an Hertz, der sie zuerst mit Hilfe des Funkens erzeugte und nachwies. Gedenket besonders auch Liebens, der in der elektrischen Ventilröhre ein unvergleichliches Spürorgan für elektrische Schwingungen erdachte, das sich zugleich als ideal einfaches Instrument zur Erzeugung elektrischer Schwingungen herausstellte. Gedenket dankbar des Heeres namenloser Techniker, welche die Instrumente des Radio-Verkehres so vereinfachten und der Massenfabrikation anpassten, dass sie jedermann zugänglich geworden sind.

Sollen sich auch alle schämen, die gedankenlos sich der Wunder der Wissenschaft und Technik bedienen und nicht mehr davon geistig erfasst haben als die Kuh von der Botanik der Pflanzen, die sie mit Wohlbehagen frisst.

Denket auch daran, dass die Techniker es sind, die erst wahre Demokratie möglich machen. Denn sie erleichtern nicht nur des Menschen Tagewerk, sondern machen auch die Werke der feinsten Denker und Künstler, deren Genuss noch vor kurzem ein Privileg bevorzugter Klassen war, der Gesamtheit zugänglich und erwecken so die Völker aus schläfriger Stumpfheit.

Was speziell den Rundfunk anlangt, so hat er eine einzigartige Funktion zu erfüllen im Sinne der Völkerversöhnung. Bis auf unsere Tage lernten die Völker einander fast ausschließlich durch den verzerrenden Spiegel der eigenen Tagespresse kennen. Der Rundfunk zeigt sie einander in lebendigster Form und in der Hauptsache von der liebenswürdigen Seite. Er wird so dazu beitragen, das Gefühl gegenseitiger Fremdheit auszutilgen, das so leicht in Misstrauen und Feindseligkeit umschlägt.

Betrachtet in dieser Gesinnung die Ergebnisse des Schaffens, welche diese Ausstellung den staunenden Sinnen des Besuchers darbietet.”
