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 a champion of endangered orangutans, passed away at the age of 79. Her legacy, marked by decades of groundbreaking research and tireless advocacy, leaves a profound impact on the world of conservation and the understanding of great apes. Alongside Jane Goodall and Dian Fossey, Galdikas was one of the three prominent researchers of great apes often referred to as the “trimates.” Each of these women dedicated their lives to studying and protecting primates, leaving an indelible mark on science and conservation efforts.
Galdikas’s journey began in the early 1960s when she moved to Indonesia to study orangutans, a species she had chosen after being inspired by the work of her mentor, the renowned primatologist Louis Leakey. At the time, little was known about orangutans, and many believed that they were not capable of forming complex social structures. Galdikas’s research in the remote rainforests of Borneo challenged these assumptions, revealing the intricate social lives and cognitive abilities of these apes.
In 1971, Galdikas established her research camp in a remote rainforest in Borneo, an area devoid of transportation and communication services. The camp was home to leeches, malarial mosquitoes, wild pigs, and king cobras, presenting a daunting environment for any researcher. Despite these challenges, Galdikas persevered, immersing herself in the lives of the orangutans she studied. Her dedication and commitment to her research led to groundbreaking discoveries about the social behaviors and ecological roles of orangutans, fundamentally altering our understanding of these remarkable creatures.
Galdikas’s work not only advanced scientific knowledge but also inspired a new generation of conservationists. Her research highlighted the critical need to protect the habitats of orangutans, which were being threatened by deforestation and human encroachment. In response, she founded the Borneo Orangutan Survival Foundation (BOSF) in 1986, an organization dedicated to the conservation of orangutans and their ecosystems. Under her leadership, BOSF implemented rehabilitation programs for orangutans that had been displaced by human activities, providing them with a chance at survival in the wild.
Throughout her career, Galdikas received numerous accolades for her contributions to science and conservation. In 1988, she became the first woman to receive a MacArthur Fellowship, often referred to as the “Genius Grant,” in recognition of her groundbreaking work. She was also awarded the National Medal of Science in 2016, the highest honor bestowed upon scientists in the United States.
Biruté Galdikas’s passing is a significant loss for the scientific community and the world of conservation. Her life’s work has left an indelible mark on our understanding of great apes and the importance of their protection. As we remember her, we are reminded of the power of dedication, perseverance, and the profound impact that one individual can have on the world. Galdikas’s legacy will continue to inspire future generations of researchers and conservationists, ensuring that the plight of orangutans and other endangered species remains a priority for the global community.
