|11 April 1862||1915 Bruce Medalist||14 June 1938|
Wallace Campbell studied civil engineering at the University of Michigan, then taught astronomy there from 1888 to 1891. In 1890 he worked as a summer volunteer at Lick Observatory where he learned spectroscopy under James E. Keeler, whom he succeeded the following year. From 1900 to 1930 he was director of Lick, although for the last seven years he was actually at Berkeley as president of the University of California. After important spectroscopic studies of Mars, hot stars, nebulae and Nova Aurigae, he headed a vast program of photographically measuring radial velocities of stars. He founded the Lick southern station in Chile and designed the Mills spectrographs. He discovered numerous spectroscopic binaries, and he determined the motion of the solar system with respect to surrounding stars. He also led a number of eclipse expeditions, one of which (in 1922) confirmed the Einstein deflection of light by the sun.
