Margaret Harwood
Margaret Harwood (March 19, 1885 – February 6, 1979) was an American astronomer who specialized in photometry, which involved measuring variation in the light of stars and asteroids. In 1916, at 30 years old, Harwood was named director of Maria Mitchell Observatory, and worked there until her retirement in 1957. In 1917, she discovered the asteroid 886 Washingtonia four days before its formal recognition, but was advised not to report it because it would have been inappropriate for a woman to do so. In 1923, she became the first woman to gain access to the Mount Wilson Observatory, and in 1924 was the first woman allowed to use the observatory's 60-inch telescope, the largest in the world at the time. In 1960, an asteroid discovered at Palomar was named in her honor as 7040 Harwood.
