Dian Fossey
1932–1985 · Primatologist & Conservationist
Dian Fossey was a primatologist who spent 18 years living among mountain gorillas in Rwanda. Her work transformed our understanding of gorillas, but she was murdered — possibly by poachers — in 1985.
“The more you learn about the dignity of the gorilla, the more you want to avoid people.”
Fossey lived alone in a remote mountain camp in Rwanda for 18 years, sitting with wild gorillas every day until they accepted her as one of their own.
Why is this scientist famous?
Studied mountain gorillas for 18 years and was murdered fighting to protect them.
Dian Fossey lived among mountain gorillas and fought to protect them from extinction. Because of her work, these gentle giants are still with us today. Her story shows how one person's dedication can save an entire species, and it inspired a global movement to protect wildlife and the habitats they depend on.
Dian's story
Early Life
Born in 1932 in San Francisco, Fossey was fascinated with animals from childhood. She originally trained as an occupational therapist and worked in a children's hospital. But after reading George Schaller's work on mountain gorillas and visiting Africa in 1963, she dedicated her life to studying them.
Karisoke Research Center
In 1967, Fossey established the Karisoke Research Centre in the Virunga Mountains of Rwanda, at an altitude of 3,000 meters. She lived alone in a tent, then a cabin, surrounded by rainforest and volcanoes. She slowly habituated the gorillas to her presence by imitating their behavior, eating their food, and making their sounds.
Gorilla Families
Fossey gave gorillas names like Digit, Beethoven, and Uncle Bert. She documented their family structures, personalities, and emotional lives. She discovered that gorillas are gentle, intelligent, and deeply social — not the aggressive monsters of popular myth. Her 1983 book Gorillas in the Mist became a bestseller and a film starring Sigourney Weaver.
Conservation and Murder
Fossey became increasingly focused on anti-poaching work, destroying traps and confronting poachers. In 1977, her beloved gorilla Digit was killed by poachers, devastating her. On December 26, 1985, she was found murdered in her cabin, hacked with a machete. The case was never solved. Many believe she was killed by poachers she had been fighting.
What did they discover?
18-Year Study of Mountain Gorillas
Conducted the longest continuous field study of mountain gorillas, revealing their social structures, intelligence, and gentle nature.
Karisoke Research Center
Founded the Karisoke Research Centre in 1967, which continues to operate and is now one of the world's most important primate research facilities.
Anti-Poaching Campaign
Pioneered active anti-poaching patrols in Rwanda, helping to save mountain gorillas from extinction.
Amazing facts
She lived alone in a remote mountain camp in Rwanda at 3,000 meters altitude for 18 years.
She gave each gorilla a name like Digit, Beethoven, and Uncle Bert — and they accepted her as part of their family.
She was found murdered in her cabin on December 26, 1985 — the case was never solved.
Her book Gorillas in the Mist was made into a film starring Sigourney Weaver in 1988.
She was friends with Jane Goodall, who was also studying primates in Africa.
Mountain gorillas are the only great ape whose population is increasing, partly thanks to her conservation work.
