No IQ test was ever administered to Einstein. The “160” is a popular estimate from biographical analysis — and he rejected the idea of IQ as a measure of his work.
A compass, a violin and a “holy” geometry book
Born in Ulm on 14 March 1879 to a secular Jewish family; they moved to Munich a year later, where his father and uncle ran an electrical-engineering firm. At about five, a compass his father showed him — a needle moved by something invisible — left what he later called a deep and lasting impression.
His mother had him take violin lessons from six; Mozart became a lifelong love. A family friend, the medical student Max Talmud, brought him popular-science books, and at twelve he worked through a geometry textbook he called his “holy little geometry book”.
Education: not the failing student of legend
The myth that he failed maths is false. His 1896 school-leaving certificate from Aarau survives: on the Swiss scale 6 is the top mark, and he got it in every maths subject.
Catholic elementary school, where he was top of his class.
Strong in maths and science but hated the rote drill; left at 15 without a diploma after his family moved to Italy.
Sat it at 16, two years early. Excelled in maths and physics, failed the general sections.
A liberal school run on Pestalozzi's principles; he flourished and earned the Matura on the left.
Diploma to teach mathematics and physics. Often skipped lectures, relying on friend Marcel Grossmann's notes.
Thesis “A New Determination of Molecular Dimensions”, which became one of his most-cited papers.
Habilitation, qualifying him to lecture — his first step into academia.
1905: four papers from a patent clerk
His “miracle year”, written in the evenings while he worked six days a week at the patent office.
Send a twin to the stars
Moving clocks run slow. One twin stays home for 10 years; the other flies away and back at the speed you choose.
General relativity followed in 1915, recasting gravity as the curvature of spacetime. Its 1919 confirmation during a solar eclipse made him world-famous overnight. His Nobel Prize (awarded in 1922 for 1921) was for the photoelectric effect, not relativity.
Beyond 1905: the rest of the work
More than 300 scientific papers in all. These are the ones that still shape physics, plus the books he wrote for everyone else.
His “happiest thought”: a falling person feels no gravity — the seed of general relativity.
Argued light must be both wave and particle.
The field equations: gravity as curved spacetime; also explained Mercury's orbit.
Predicted ripples in spacetime, first detected by LIGO in 2015.
His popular explanation for general readers.
The physics behind lasers; and the first relativistic model of the universe, with the cosmological constant.
His Princeton lectures in book form.
With Satyendra Nath Bose: predicted a new state of matter, created in the lab in 1995.
A patented fridge with no moving parts, designed with Leo Szilard.
With Podolsky and Rosen: challenged quantum mechanics — now the basis of quantum entanglement research.
With Rosen: the first description of what are now called wormholes.
Essays on politics, religion and pacifism.
Left Germany as the Nazis took power and joined the Institute for Advanced Study, where he spent his last two decades.
Signed a warning that Germany might build an atomic bomb. He later called it a great mistake, and did not work on the Manhattan Project.
“I have no special talents. I am only passionately curious.”

Reading the ≈160
Not from Cox, and not from any test. A popular estimate that became a benchmark — which gives it a precision it has never had.
