Campbell, William Wallace


Born Apr. 11, 1862, in Hancock, Ohio; died June 14, 1938, in San Francisco. American astronomer.

Campbell was in charge of the Lick Observatory in California from 1901 to 1930. His studies were devoted to astronomical spectroscopy (the calculation of the radial velocities of stars, spectral investigations of the atmosphere of Mars). He also conducted observations of the sun during eclipses. Campbell calculated the velocities and direction of the motion of the sun in space from the radial velocities of stars (1911).
