In 1908 he became an astronomer and instrument maker at the Mount Wilson Observatory. Among his designs was the 100-inch (2,500 mm) telescope at that observatory, and a 50-foot (15 m) interferometer that he used to measure star diameters. Gene Shoemaker used Pease's high quality photographs of the Moon to make its first geologic map. [1]
