When Did Dian Fossey Die?

Dian Fossey was an American primatologist and conservationist known for undertaking an extensive study of mountain gorilla groups from 1966 until her murder in 1985. She studied them daily in the mountain forests of Rwanda, initially encouraged to work there by paleoanthropologist Louis Leakey. Gorillas in the Mist, a book published two years before her death, is Fossey's account of her scientific study of the gorillas at the Karisoke Research Center and prior career.
