Albert Einstein (1879 to 1955) was a German-born theoretical physicist whose work rebuilt the way we describe space, time, gravity and light. In a single year, 1905, while working as a junior examiner at the Swiss Patent Office in Bern, he published four papers that reset three separate fields of physics at once. Over the following decade he developed the general theory of relativity, which recast gravity as the bending of spacetime and replaced the framework Isaac Newton had held for more than two centuries. He is often reduced to a single equation and a shock of white hair, but the record is more precise and more interesting than the caricature. His prediction that starlight curves as it passes the Sun was tested during a total solar eclipse in 1919 and turned him into a public figure almost overnight. His Nobel Prize in Physics for the 1921 prize year went not to relativity but to his account of the photoelectric effect, one of the first pillars of quantum theory. His later years, spent in exile in the United States after 1933, tied his science to the hardest moral questions of the century, including the atomic weapon he helped set in motion but never built.

Early life

Einstein was born on 14 March 1879 in Ulm, in the Kingdom of Württemberg in the German Empire, to Hermann and Pauline Einstein, a secular Jewish couple. The family moved to Munich the year after his birth, where Hermann and his brother Jakob ran an electrical engineering firm that made equipment based on direct current. A younger sister, Maja, was born in 1881 and remained close to him throughout his life. Several tidy legends attach to his childhood, and most do not survive contact with the evidence. He was slow to begin speaking, which worried his parents, but the widely repeated claim that he failed at mathematics is false. By his early teens he had worked through algebra and Euclidean geometry, and he taught himself calculus ahead of his schooling. What he genuinely disliked was the rote, authoritarian style of the Luitpold Gymnasium in Munich, which sat badly with a boy who preferred to reason a problem out for himself. He took up the violin as a child and kept it as a companion for the rest of his life, often turning to music while thinking through a problem. When Hermann's business faltered in the mid-1890s, the family relocated to northern Italy, first to Milan and then to Pavia, leaving the teenage Albert behind to finish school in Munich. He soon left the gymnasium without a diploma and joined his family in Italy. In 1895 he sat the entrance examination for the Swiss Federal Polytechnic in Zurich, later known as ETH Zurich, two years below the usual age. He scored well in mathematics and physics but fell short in the general subjects, and was advised to complete his secondary education first. He did so at the cantonal school in Aarau, whose freer atmosphere suited him, boarding with the family of his teacher Jost Winteler. Around this time Einstein renounced his German citizenship, in part to avoid compulsory military service, and he remained stateless for several years before becoming a Swiss citizen in 1901. He entered the Zurich Polytechnic in 1896 to train as a mathematics and physics teacher and graduated in 1900. Steady academic employment did not follow at once. In 1902 a friend's father helped him secure the post at the patent office in Bern, a job that left him enough spare hours to pursue his own research. It was from that desk, and not from a university chair, that his most productive year came.

The miracle year and relativity

In 1905 Einstein published four papers in the German journal Annalen der Physik in a burst now called his annus mirabilis, or miracle year. Each would have secured a lesser reputation on its own. The first proposed that light behaves as discrete packets of energy, or quanta, and used the idea to explain the photoelectric effect, the way certain metals release electrons when struck by light. The second treated the jittery motion of tiny particles suspended in a fluid, known as Brownian motion, and gave strong quantitative evidence that atoms and molecules are real physical objects rather than a convenient fiction. The third paper introduced the special theory of relativity. Starting from two simple postulates, that the laws of physics hold in all uniformly moving frames and that the speed of light in a vacuum is the same for every observer, Einstein showed that measurements of time and length depend on the motion of the observer, and that there is no universal "now" shared by everyone. The fourth paper, a short follow-up, drew out a consequence that has since become the most quoted line in physics: mass and energy are two forms of the same thing, related by E = mc squared. That same year the University of Zurich accepted his doctoral dissertation. Special relativity described uniform motion but left out gravity and acceleration. Einstein spent the next ten years closing that gap, guided by the insight that a person in free fall feels no gravity at all. The result, presented to the Prussian Academy of Sciences in November 1915 and published in full in 1916, was general relativity. It reframed gravity not as a force reaching across empty space but as the curving of spacetime by mass and energy, with objects following the straightest available paths through that curved geometry. The theory made a testable prediction. Light from a distant star, grazing the edge of the Sun, should be deflected by about 1.75 arcseconds, twice the value implied by Newton's physics. Confirming it required a total solar eclipse to blot out the Sun's glare. On 29 May 1919 two British expeditions set out to make the measurement, one led by Arthur Eddington to the island of Príncipe off West Africa, the other to Sobral in Brazil. Despite clouds and heat-warped instruments, the results matched Einstein's figure more closely than Newton's. On 6 November 1919 the findings were announced at a joint meeting of the Royal Society and the Royal Astronomical Society in London. The next morning the press carried the news around the world, and a working physicist became one of the most famous people alive.

Fame, exile and later life

Recognition from his own field followed. The Royal Swedish Academy of Sciences awarded Einstein the Nobel Prize in Physics for the 1921 prize year, though the decision was actually reached in 1922 after the committee reserved the 1921 award. The citation honoured him "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." Relativity, still contested at the time, went unmentioned in the official wording. Under the terms of his divorce from his first wife, Mileva Marić, Einstein had agreed to give her the prize money, and he did. Through the 1920s Einstein travelled widely and became a recognisable global celebrity, a role no theoretical physicist had held before. That visibility grew dangerous as antisemitism and the Nazi movement rose in Germany. He was abroad in early 1933 when Adolf Hitler came to power, and he did not return. He gave up his German citizenship a second time, saw his property seized and his work denounced, and accepted a position at the newly created Institute for Advanced Study in Princeton, New Jersey. He settled there for the rest of his life and was naturalised as a United States citizen on 1 October 1940. His fame carried into politics. On 2 August 1939 Einstein signed a letter to President Franklin D. Roosevelt, drafted largely by the physicist Leó Szilárd, warning that recent work on nuclear fission might allow Germany to build "extremely powerful bombs" and urging the United States to begin its own research. The Einstein–Szilard letter is widely credited with helping start the chain of decisions that became the Manhattan Project. Einstein himself, viewed as a security risk, was never cleared to work on the bomb, and after the war he described signing the letter as the one great mistake of his life. In his American years Einstein spoke out on causes beyond physics. He was an outspoken pacifist for most of his life, a supporter of the civil rights movement who corresponded with W.E.B. Du Bois and befriended the singer Paul Robeson, and a public critic of racial segregation. In 1952, after the death of Israel's first president Chaim Weizmann, the Israeli government offered Einstein the presidency. He declined, saying he lacked both the aptitude and the experience to deal with people in an official role. His last research years were spent chasing a unified field theory that would join gravity and electromagnetism in one framework, a goal he never reached. He died in Princeton on 18 April 1955 of a ruptured abdominal aortic aneurysm, having refused surgery with the words that he had done his share and wished to go without artificial prolonging.

Legacy

Einstein's physics stopped being abstract long ago. The satellite-navigation system in an ordinary phone corrects for both special and general relativity, because clocks in orbit tick at a measurably different rate from clocks on the ground, and without those corrections positions would drift by kilometres a day. The mass-energy relation sits behind nuclear power and the physics of stars. In 2015 and 2016 the LIGO detectors recorded gravitational waves from two colliding black holes, confirming a ripple in spacetime that Einstein had predicted in 1916 and doubted anyone would ever measure. His 1905 work on light quanta helped launch quantum mechanics, the theory that governs semiconductors, lasers and solar cells. It is a lasting irony that Einstein never fully accepted the theory he helped found, objecting to its reliance on probability with the remark, often paraphrased, that God does not play dice. In 1935 he and his colleagues Boris Podolsky and Nathan Rosen published a thought experiment, now called the EPR paradox, meant to expose what they saw as the theory's incompleteness. Instead it identified quantum entanglement, a phenomenon at the centre of quantum computing and cryptography research today. Beyond the laboratory, Einstein became the modern shorthand for the scientific mind, his face and name attached to institutions from the Albert Einstein College of Medicine to the Albert Einstein Archives at the Hebrew University of Jerusalem, which he helped found and to which he left his personal papers and the rights to his image. That archive of tens of thousands of documents, rather than any single legend, is why we can still separate what Einstein actually did from what has been invented about him.

Why we keep his story

Einstein's life is documented so fully because so much of it was written down and kept: manuscripts, more than eighty thousand letters, drafts, and even the offer of a presidency he turned down in a signed reply. That paper trail is the reason the myths can be checked and, often, corrected. We know he did not fail mathematics, we know exactly which four papers he wrote in 1905, and we can read his own words of regret about the letter to Roosevelt, because someone chose to preserve the originals rather than the story about them. Most lives leave a far thinner record, and the details go first: the reasons behind a decision, the tone of a voice, the small events that a family remembers and then forgets within a generation or two. Confinity exists to help ordinary lives keep the kind of record that scholars had to reconstruct for Einstein, so that a person is understood through their own documents and words rather than through a flattened summary. A well-kept archive does not make anyone a genius. It does make it possible for the people who come later to meet the real person, contradictions included, instead of a convenient legend.
