World-renowned primatologist, anthropologist and conservationist Dame Jane Goodall has died at the age of 91 in California, United States. The Jane Goodall Institute confirmed that she passed away of natural causes while on a trip.

Her groundbreaking research revealing the close relationship between humans and chimpanzees brought a revolution in scientific thought. She was also an outspoken voice against climate change and deforestation, dedicating her life to global conservation efforts.

The United Nations expressed deep sorrow at her death, saying, “She leaves behind an extraordinary legacy for humanity and nature.”

Bangladesh’s Chief Adviser Muhammad Yunus, in a condolence message, said, “Nature has lost one of its greatest voices. Her work will continue to influence the world long after her physical absence.”

Calling the death “heartbreaking,” Greenpeace described her as “a true conservationist of our time.” Greenpeace UK’s Co-Executive Director Will McCallum said, “Dr. Goodall’s legacy lives not only in science but also in the global movement to protect nature and build a better world.”

Born in London in 1934, Jane Goodall showed a deep interest in animals from an early age. Her pioneering research on chimpanzees in Tanzania challenged conventional scientific ideas and opened new horizons in evolutionary science.

In 1977, she founded the Jane Goodall Institute, which continues to work for chimpanzee conservation and environmental protection. She was honored with the title of Dame in 2003 and received the U.S. Presidential Medal of Freedom in 2025.

Just a week before her death, she gave an interview at an event in New York. She was scheduled to deliver a speech in California on October 3, for which all tickets had already been sold out.
