Prior to her fame, the Canadian primatologist and anthropologist Biruté Mary Galdikas, along with her husband, Rod Brindamour came to the Tanjung Puting Reserve in Indonesian Borneo when the forest was under siege. The year was 1971, and coming to this tropical, humid rainforest would have sounded almost surreal. There was no telephone, road, electricity, television or postal service. And Illegal logging and hunting were stripping animals of the forests they depended on for survival.However, they came to study orangutans, an exceptionally intelligent non-human species found only in Borneo and Sumatra, whose habitat was also under threat. The orangutans Galdikas had come to study were considered particularly difficult subjects, elusive, wary and living largely in dense, swampy forests.Before her departure from America, Galdikas was informed by professors and others that the study of orangutans in the wild “couldn’t be done.” But she had other plans for herself and wildlife.Also Read: Wheat farmers have a new weapon against a pest that costs them $350 million a year; researchers are using straw bales to move tiny parasitoids into fields and fight the wheat stem sawflyA childhood fascination with the forests of BorneoBorn in 1946 in Wiesbaden, Germany, Biruté Galdikas was the daughter of Lithuanian refugees Antanas and Filomena Galdikas, who were on their way to Canada to settle there after World War II.Galdikas’ passion for exploration developed when she was a little girl growing up in Toronto. As per the Orangutan Foundation International (OFI), her first library book was Curious George which she had borrowed at the age of six. The stories of the naughty monkey along with the yellow-hatted man inspired her and by the time she was in the second grade, she had made up her mind that she would become an explorer.She received her education at Canadian universities before moving to America. She majored in natural sciences at the University of California at Los Angeles where she acquired her bachelor’s degree in psychology and zoology in the year 1966 and masters in anthropology in the year 1969.While in graduate school, she was introduced to a renowned Kenyan anthropologist, Dr. Louis Leakey. She discussed with him her dream of studying orangutans. Initially, he seemed indifferent, but she kept pursuing her dreams. After three years, Leakey secured funding for her research, following the support he had previously given Jane Goodall and Dian Fossey for their studies of chimpanzees and mountain gorillas. Then came the journey to Borneo.Building a research camp in the wildUpon arrival at Tanjung Puting, an untouched coastal national park, Galdikas started observing the ecology and behavior of the orangutans in the wild. She set up a camp named Camp Leakey after her professor. This task required a lot of patience on Galdikas’ part since orangutans are often found in the forest canopies and are far from the observer.Four years after going to Borneo, Galdikas brought her research to a wider public through writing the feature cover story in National Geographic Magazine. Brindamour provided the photos for her publication.When Biruté Galdikas entered Borneo’s remote swamps in 1971, she was told studying wild orangutans was nearly impossible. (An image of her with an orangutan/Instagram: drbirute)Decades of watching orangutans changed what scientists knewThe research conducted by Galdikas brought many insights into the lives of orangutans and contributed to greater knowledge of the species among scientists. According to OFI, she discovered the unusually long period between births of orangutans, on average lasting for 7.7 years at Tanjung Puting.Furthermore, she identified over 400 different foods eaten by the primates and provided considerable data regarding their ecology. Her research let scientists to learn more about the social structure and mating habits of orangutans.However, her efforts went beyond simply studying the animals. Galdikas started working on the protection of the forests and communities around the animals. According to OFI, after four decades in Tanjung Puting, a national park now, Galdikas conducted the most extended study ever done by one main researcher of any wild mammal in the world.Biruté Galdikas began studying wild orangutans in Borneo's rainforests in 1971.

This foundation was created to help with her activities at Camp Leakey but aimed to increase conservation work for protecting orangutans and their rainforest habitat. OFI says that the organisation works in three fields – conservation, research and education and is devoted to the protection of wild, captive and formerly captive orangutansNowadays OFI manages Camp Leakey situated in Tanjung Puting National Park and Orangutan Care Center and Quarantine located near Pangkalan Bun and, according to OFI, is a shelter to 330 displaced orangutans.Another field of her conservation work was connected with the environmental policy in Indonesia. Galdikas was a senior adviser on orangutan issues for the Ministry of Forestry of Indonesia from March 1996 till March 1998 by the special decree of Indonesia’s government.In 1997 Galdikas was awarded the Kalpataru award for her contribution into the environment protection; she was the only one born outside Indonesia and among the first women who received this award. She passed away in March this year after dedicating her life to studying the exceptionally intelligent non-human species.
