Simpson, George Gaylord, 1902-1984
George Gaylord Simpson (1902-1984) was Curator of the Department of Geology and Paleontology at the American Museum of Natural History from 1945 to 1959. He first joined the staff in 1927, but left to serve in World War II in North Africa. Simpson became curator upon his return. Before this appointment, he earned his PhD in Geology from Yale and served as a Professor of Zoology at Columbia University. After his time at the American Museum of Natural History, Simpson was Curator of the Museum of Comparative Zoology at Harvard University from 1959 to 1970 and a Professor of Geosciences at the University of Arizona from 1968 until he retired in 1982.
Simpson was a major participant in the modern synthesis—a movement in the 20th century that combined Darwinian and Mendelian philosophies regarding evolution. His work primarily concerned evolutionary theory and the intercontinental migrations of extinct mammals. Simpson’s most prominent works were Tempo and Mode in Evolution, which was published in 1944, and Major Features in Evolution, published in 1953.
