John August Anderson

John August Anderson ( born August 7, 1876 in Rollag in the U.S. state of Minnesota, † December 2, 1959 in Altadena, California ) was an American astronomer.

He received his doctorate in 1907 at Johns Hopkins University and remained there afterwards. In 1908 he was appointed professor of astronomy at the same university. In 1909 he assumed responsibility for the Rowland engraving machine for producing diffraction gratings. Their quality was considered excellent, especially in terms of concave grating structures.

In 1916 he left the university to work at Mount Wilson Observatory. he remained there until 1956. His most notable contribution was his use of the Michelson interferometer for the measurement of close-set double stars.

The Anderson crater on the Moon is named after him.
