Annie Jump Cannon (December 11, 1863 - April 13, 1941) was an American astronomer. In 1896 Cannon became a member of Pickering's women, the women hired by Harvard Observatory director Edward Charles Pickering to complete the Draper Catalog mapping and defining all the stars in the sky to photographic magnitude of about 9. Henrietta Swan Leavitt (July 4, 1868 - December 12, 1921) was an American astronomer. A graduate of Radcliffe College, she worked at the Harvard College Observatory as a human computer. Though she received little recognition in her lifetime, Leavitt's discovery provided astronomers with the first standard candle with which to measure the distance to faraway galaxies.
