Michelson, Albert Abraham (1852–1931)
Albert Michelson was a German-born US physicist. In 1887 he conducted an experiment with Edward Morley to determine the velocity of the Earth
through the ether, using an interferometer of his own design. The result of the Michelson-Morley
experiment is now seen as a key piece of evidence for the special
theory of relativity. Michelson also determined the speed
of light and became the first US physicist to win a Nobel Prize, receiving
the 1907 award in physics.
