Alfred H. Joy (1882-1973) was an astronomer at the Mount Wilson Observatory from 1915 to 1973 who measured spectroscopic parallaxes and radial velocities of stars and studied variable stars. He invented the T Tauri classification.

Gerald Clemence (16 August 1908 — 22 November 1974) was an American astronomer. Inspired by the life and work of Simon Newcomb, his career paralleled the huge advances in astronomy brought about by the advent of the electronic computer. Clemence did much to revive the prestige of the U.S. Nautical Almanac Office.
