Harlow Shapley, American Astronomer
Harlow Shapley (November 2, 1885 - October 20, 1972) was an American astronomer. He is notable for his groundbreaking 1918 work using Cepheid variables to estimate the size of the Milky Way Galaxy and the sun's position within it as well as in 1953 proposing the Liquid Water Belt theory, now known as the concept of a habitable zone. He married Martha Betz in April 1914. She assisted her husband in astronomical research both at Mount Wilson and at Harvard Observatory. She produced numerous articles on eclipsing stars and other astronomical objects. He is also known to have incorrectly opposed Edwin Hubble's observations that there are additional galaxies in the universe other than the Milky Way. Shapley fiercely critiqued Hubble and regarded his work as junk science. Hubble's findings went on to fundamentally reshape the scientific view of the universe. In the 1940s, Shapley helped found government funded scientific associations, including the National Science Foundation. He is also responsible for the addition of thes in UNESCO (United Nations Educational, Scientific and Cultural Organization). He died in 1972 at the age of 86
