Biruté Galdikas, Champion of Endangered Orangutans, Dies at 79
With Jane Goodall and Dian Fossey, she was one of three prominent researchers of great apes who were sometimes called the “trimates.”

Biruté Galdikas, a pioneering primatologist and champion of endangered orangutans, passed away at the age of 79. Her legacy, marked by decades of groundbreaking research and unwavering dedication to the conservation of Bornean orangutans, leaves a profound impact on the world of science and environmental advocacy.
Galdikas, often referred to as one of the “trimates” alongside Jane Goodall and Dian Fossey, was a trailblazer in the study of great apes. These three women revolutionized our understanding of primate behavior and ecology, each focusing on a different species: Goodall with chimpanzees in Tanzania, Fossey with gorillas in Rwanda, and Galdikas with orangutans in Borneo.
Born in 1946 in Lithuania, Galdikas’s passion for primatology began at a young age. She moved to the United States to study at the University of California, Berkeley, where she earned her Ph.D. in 1975. Her doctoral work, supervised by renowned primatologist Louis Leakey, focused on the social structure and ecology of orangutans in the rainforests of Borneo.
In 1971, Galdikas embarked on a journey that would define her career. She traveled to the remote rainforests of Borneo, where she established a research camp in a region devoid of transportation and communication services. The challenges were immense, with leeches, malarial mosquitoes, wild pigs, and king cobras posing constant threats. Despite these obstacles, Galdikas persevered, immersing herself in the lives of the orangutans she sought to understand.
Her research revealed that orangutans are highly intelligent, capable of using tools and exhibiting complex social behaviors. Galdikas’s work challenged previous assumptions about the species, demonstrating their remarkable cognitive abilities and social structures. This groundbreaking research not only enriched our knowledge of orangutans but also expanded the field of primatology as a whole.
Galdikas’s dedication to orangutan conservation extended beyond her research. She co-founded the Borneo Orangutan Survival Foundation (BOSF) in 1986, which focuses on rehabilitating orangutans that have been orphaned due to human activities such as deforestation and poaching. Under her leadership, the organization has played a crucial role in rescuing and rehabilitating thousands of orangutans, helping them return to the wild or live in sanctuaries.
Throughout her career, Galdikas received numerous accolades for her work, including the National Geographic Society’s Buffett Award for Leadership in Conservation and the Order of the British Empire. Her autobiography, “Reflections of Eden,” provides a compelling account of her journey and the challenges she faced in her pursuit of knowledge and conservation.
Biruté Galdikas’s death is a loss not only for the scientific community but also for the orangutans she devoted her life to protecting. Her legacy, however, endures through the lives of the orangutans she helped save and the countless individuals inspired by her courage and determination. As we mourn her passing, we are reminded of the enduring impact of her work and the urgent need to continue her mission in preserving the world’s great apes and their habitats.
