Who he was (60 seconds)

Albert Einstein (1879–1955) was a German-born theoretical physicist who spent the first half of his career in Switzerland and Germany and the second at the Institute for Advanced Study in Princeton, New Jersey. He is best known for:

What he did not do

The three facts to carry away

  1. 1905 changed physics. Four papers in one year, written while he was a patent-office clerk, are the foundation of his reputation — not the later celebrity.
  2. The Nobel Prize was for light quanta, not relativity. The 1921 prize (awarded 1922) explicitly cited “the discovery of the law of the photoelectric effect.”
  3. His later career was a long argument with quantum mechanics. He helped found quantum theory and then spent thirty years disputing its standard interpretation.
