Lithuanian-Canadian primatologist conservationist
Birutė Galdikas (born 10 May 1946 in Wiesbaden; died 24 March 2026 in Los Angeles) was a Canadian primatologist, anthropologist and conservationist of Lithuanian origin. She devoted more than five decades to the study and protection of orangutans in Borneo. Alongside Jane Goodall and Dian Fossey, she was one of the researchers supported by Louis Leakey who fundamentally changed the study of great apes.
Galdikas was born after the Second World War in a German refugee camp. Her parents came from Lithuania and later moved the family to Canada. She grew up in Toronto and studied first in Vancouver, later at the University of California, Los Angeles. There she worked in psychology, zoology and anthropology. Her meeting with Louis Leakey became decisive because he supported her plan to study wild orangutans over the long term in their own habitat.
In 1971 Galdikas went to Tanjung Puting in Kalimantan, Borneo. There she founded Camp Leakey, named after her mentor. The conditions were difficult: swamp forest, heat, disease, poor routes and almost no communication. That is part of why her work mattered scientifically. Orangutans were then far less studied than chimpanzees or gorillas. Galdikas observed their social behavior, diet, long birth intervals and relationship with the forest over exceptionally long periods.
Field research increasingly became practical conservation work. Galdikas worked to protect orangutan habitat, supported the rehabilitation of confiscated or orphaned animals and drew attention to poaching, illegal wildlife trade and deforestation. In 1986 she founded Orangutan Foundation International. Her work connected science, conservation, political advocacy and local cooperation. It showed that the study of a species cannot be separated from the question of whether its habitat survives.
Galdikas became internationally known through National Geographic and later documentaries. Her name stood for another kind of research: patient, long-term, close to individual animals and at the same time directed toward whole ecosystems. Her closeness to rehabilitated orangutans brought recognition, but also discussions about methods and the limits of human care for wild animals. Those debates are part of the history of modern primatology and species conservation.
Birutė Galdikas died in Los Angeles on 24 March 2026. Her life's work remains connected with Camp Leakey, with orangutan protection and with long-term research that treated patience as a scientific strength. Her work made visible how closely the lives of individual animals, the future of a rainforest and human responsibility are connected.
