Michelson, Albert Abraham


Born Dec. 19, 1852, in Strelno (now Strzelno, Poland); died May 9, 1931, in Pasadena, Calif. American physicist.

In 1854, Michelson emigrated to the USA with his parents. He graduated from the US Naval Academy in 1873, and from 1873 to 1881 he served in the navy and taught at the academy. From 1880 to 1882 he studied at the universities of Berlin, Heidelberg, and Paris. Between 1883 and 1889, Michelson was a professor at the Case School of Applied Science in Cleveland, Ohio. From 1889 to 1892 he taught at Clark University in Worcester, Mass. Between 1892 and 1929 he was a professor at the University of Chicago. He was also president of the National Academy of Sciences from 1923 to 1927.

Michelson made measurements of the velocity of light between 1878 and 1882 and between 1924 and 1926 that long remained unsurpassed in accuracy. In 1881 he proved experimentally and in 1885-87 with E. W. Morley confirmed the independence of the velocity of light from that of the earth. These studies constituted the experimental foundation of the special theory of relativity. In his experiment Michelson used an interferometer he invented, with which he measured the spectral lines of different elements in 1892-93. He proposed that the wavelength of the red line of cadmium be taken as the standard of length. Michelson also constructed a spectral instrument with a super-high resolution. He devoted the last years of his life to the determination of the angular diameters of stars using a stellar interferometer he built for the purpose. Michelson was awarded a Nobel Prize in 1907 for the optical instruments he designed and built and for the studies he conducted with them.
