Albert Abraham Michelson

Michelson in 1923

Albert Abraham Michelson (December 19, 1852 – May 9, 1931) was an American physicist. He was born in Strzelno (in Posen, Prussia, now in Poland) but grew up in California. He was known for his work on measuring the speed of light. That work led to him being awarded the Nobel Prize in Physics in 1907. He was the first American to receive it in the field of science.^[1]

The horizontal structure mounted at the top of the Hooker Telescope implements Michelson's stellar interferometer (1920). Mirrors on that stage (not visible in picture) redirect starlight from two smaller apertures up to 20 feet (6m) apart into the telescope.
A monument at United States Naval Academy marks the path of Michelson's experiments measuring the speed of light.
