Dian Fossey (Jan. 16 1932 – 1985) was an American zoologist who undertook a daily study of gorilla groups over a period of 18 years in the forests of Rwanda. Her book Gorillas in the Mist combines her scientific study of the mountain gorilla with her own personal story. Called one of the foremost primatologists in the world while she was alive, Fossey, along with Jane Goodall and Birute Galdikas, were the so-called "Trimates". Fossey was murdered in 1985; the case remains open.
