In 1971, Biruté Galdikas entered Borneo’s rainforest to study orangutans; more than 50 years later, her foundation has helped return over 1,000 to the wild

Biruté Galdikas began studying wild orangutans in Borneo's challenging rainforests in 1971. She established Camp Leakey, which became a site for long-running orangutan research studies. Her work significantly expanded global understanding of orangutan behavior and their ecological importance. Galdikas later founded the Orangutan Foundation International for conservation and rehabilitation efforts. Over 1,000 orangutans have been returned to their natural habitats through these projects.
