Albert Einstein
The Mind That Bent Space and Time
In 1905, a twenty-six-year-old patent clerk in Bern, Switzerland, published four papers that overturned three centuries of physics. He proved that atoms exist, explained the photoelectric effect, introduced special relativity, and derived the most famous equation in science: E = mc². His name was Albert Einstein, and within a decade he would reshape humanity's understanding of space, time, gravity, and the nature of the universe itself. He was also a refugee, a pacifist who urged the building of the atomic bomb, and a man whose personal life was as turbulent as his physics was elegant.
“Imagination is more important than knowledge.”
1879–1955
Born in Ulm, Württemberg, Germany, to a middle-class Jewish family. Died in Princeton, New Jersey, having spent his final decades as both the world's most famous scientist and a symbol of the refugee experience. Seventy-six years that redefined the physical universe.
1905
Einstein's <em>Annus Mirabilis</em> — four revolutionary papers published while working as a patent examiner in Bern. Each paper alone would have secured his place in the history of physics. Together, they constitute the most productive year any scientist has ever had.
1921
Awarded the Nobel Prize in Physics for his explanation of the photoelectric effect — not for relativity, which the Nobel Committee considered too controversial. The prize money went to his first wife Mileva as part of their divorce settlement.
1905
The mass–energy equivalence formula, derived in a three-page paper, revealed that a small amount of mass contains an enormous amount of energy. It became the theoretical foundation of nuclear power — and nuclear weapons.

Defining Events
The Miracle Year
Working six days a week at the Swiss Patent Office in Bern, Einstein published four papers that transformed physics. The first explained the photoelectric effect using quantum theory — earning him the Nobel Prize sixteen years later. The second proved that atoms exist through his analysis of Brownian motion. The third introduced special relativity, abolishing absolute time and space. The fourth derived E = mc², revealing the equivalence of mass and energy. He was twenty-six years old, had no academic position, and had been rejected for a university teaching post the year before.
General Relativity Confirmed
On November 6, 1919, the Royal Astronomical Society announced that observations of a total solar eclipse confirmed Einstein's general theory of relativity: light from distant stars was bent by the sun's gravity, exactly as Einstein had predicted. The next morning, the Times of London ran the headline: "Revolution in Science — New Theory of the Universe — Newtonian Ideas Overthrown." Einstein became the most famous scientist in the world overnight. Space and time, it turned out, were not a fixed stage but a dynamic fabric warped by mass and energy.
The Letter to Roosevelt
On August 2, 1939, Einstein signed a letter to President Franklin D. Roosevelt warning that recent advances in nuclear physics made an atomic bomb feasible — and that Germany might be pursuing one. The letter, drafted by physicist Leó Szilárd, led directly to the creation of the Manhattan Project. Einstein himself was excluded from the project on security grounds. After Hiroshima, he said: "If I had known that the Germans would not succeed in producing an atomic bomb, I would not have lifted a finger." The pacifist had helped unleash the deadliest weapon ever built.
Timeline
Born in Ulm
Born on March 14 in Ulm, Württemberg, Germany, to Hermann Einstein, a salesman and entrepreneur, and Pauline Koch. The family moved to Munich the following year, where his father and uncle Jakob, a trained engineer, ran an electrical equipment manufacturing company. Young Albert was slow to speak but showed early fascination with a compass his father gave him — the invisible force that moved the needle captivated him.
Zurich Polytechnic
Enrolled at the Eidgenössische Technische Hochschule (ETH) in Zurich after renouncing his German citizenship to avoid military service. He skipped lectures, read physics on his own, and relied on his classmate Marcel Grossmann's notes to pass exams. He also met Mileva Marić, one of the only women studying physics in Europe, who became his intellectual partner and first wife.
Patent Office in Bern
Unable to secure an academic position after graduation, Einstein took a job as a technical expert third class at the Swiss Federal Patent Office in Bern. The work was undemanding, leaving him time to think about physics during his lunch breaks and evenings. It was the most productive intellectual environment he would ever inhabit — not despite the obscurity, but partly because of it.
Annus Mirabilis
Published four groundbreaking papers: on Brownian motion (proving atoms exist), the photoelectric effect (a foundation of quantum theory), special relativity (unifying space and time), and mass–energy equivalence (E = mc²). Each paper alone would have made his career. Together, they constitute the single greatest burst of scientific creativity in recorded history.
General Relativity
After ten years of struggle, Einstein completed his general theory of relativity — a geometric theory of gravitation that described gravity not as a force but as the curvature of spacetime caused by mass and energy. The field equations were extraordinarily beautiful and extraordinarily difficult. They predicted gravitational lensing, black holes, and gravitational waves — all subsequently confirmed.
Nobel Prize in Physics
Awarded the Nobel Prize for his 1905 explanation of the photoelectric effect, not for relativity. The Nobel Committee considered relativity too speculative. As agreed in their divorce settlement, the prize money went entirely to his first wife Mileva Marić, who used it to buy three apartment buildings in Zurich.
Flight from Nazi Germany
When Hitler became Chancellor in January 1933, Einstein was visiting the United States. He never returned to Germany. The Nazis confiscated his property, revoked his citizenship, and put a bounty on his head. He accepted a position at the Institute for Advanced Study in Princeton, New Jersey, where he would spend the remaining twenty-two years of his life.
Death in Princeton
Died on April 18 at Princeton Hospital from a ruptured abdominal aortic aneurysm. He refused surgery, saying: "I want to go when I want. It is tasteless to prolong life artificially." His last words were spoken in German to a night nurse who did not understand the language. The pathologist who performed the autopsy removed his brain without the family’s permission, hoping to discover the secret of his genius.
Key Figures
Mileva Marić
A Serbian physicist and one of the first women to study at ETH Zurich, Mileva was Einstein's intellectual companion during the most creative period of his life. They married in 1903 and had three children, including a daughter born out of wedlock whose fate remains unknown. The extent of her contribution to Einstein's early work is debated by historians. Their marriage deteriorated as Einstein's fame grew; they divorced in 1919, with the Nobel Prize money going to her as part of the settlement. She spent her later years in Zurich, largely forgotten.
Niels Bohr
The Danish physicist who founded quantum mechanics and became Einstein's greatest scientific sparring partner. Their debates at the Solvay Conferences of the late 1920s — Einstein attacking quantum indeterminacy with ingenious thought experiments, Bohr defending it with devastating rebuttals — are among the most celebrated intellectual exchanges in the history of science. Einstein never accepted that "God plays dice with the universe." Bohr replied: "Stop telling God what to do." Despite their disagreements, they maintained deep mutual respect. Bohr reportedly kept a photograph of Einstein in his study until his own death in 1962.
The Legacy of Albert Einstein
Einstein changed what we mean when we say "the universe." Before him, space was a stage and time was a clock. After him, they were a single, malleable fabric warped by mass and energy. His theories predicted black holes, gravitational waves, and the expansion of the cosmos — all confirmed decades after his death. He was also a refugee who understood, from personal experience, the fragility of civilisation and the speed with which democracies can collapse into barbarism.
He spent his final decades searching for a unified field theory that would reconcile gravity with quantum mechanics — a quest that remains unfinished. But the problems he posed still drive physics today. Every GPS satellite, every nuclear reactor, every gravitational wave detector is a testament to the patent clerk from Bern who dared to ask what it would be like to ride a beam of light.
