Albert Einstein
Theoretical physicist · 1879–1955
Physicist whose theories of relativity transformed understanding of space, time, gravity and the universe.
Albert Einstein was born in Ulm, Germany, and studied at the Swiss Federal Polytechnic in Zurich. While working as a patent examiner in Bern, he published four papers in 1905 covering the photoelectric effect, Brownian motion, special relativity and the equivalence of mass and energy.
His general theory of relativity, completed in 1915, described gravity as the curvature of space and time. Observations during the solar eclipse of 1919 supported its predictions and brought him international fame. He received the 1921 Nobel Prize in Physics for his work on the photoelectric effect.
Einstein left Germany in 1933, after the Nazi party came to power, and settled in the United States, joining the Institute for Advanced Study in Princeton, New Jersey. In later years he spoke publicly on pacifism, nuclear disarmament and civil rights. He died in Princeton in 1955.

The proposal that light energy travels in discrete quanta rather than continuous waves, and what that explains about the photoelectric effect.
How the random jittering of tiny particles suspended in a liquid follows from the motion of unseen molecules, and how it can be measured.
How measurements of time and distance depend on the observer's motion, and why the speed of light is the same for everyone.
The argument that a body giving off energy loses mass, and that mass and energy are therefore two measures of the same thing.
A theory of gravity in which mass and energy curve space and time, and objects follow the shape of that curvature.
