Scientist and global activist Jane Goodall, who turned her childhood love of primates into a lifelong quest for protecting the environment, has died at the age of 91, the institute she founded said on Wednesday. Goodall died of natural causes while in California on a speaking tour, the Jane Goodall Institute said in a social media post. English Dr. Jane Goodall, chimpanzee researcher and naturalist, observes through glass some of Taronga Zoo's 25 member chimpanzee colony in Sydney, August 31. Under Leakey, Goodall set up the Gombe Stream Chimpanzee Reserve, later renamed the Gombe Stream Research Centre, near Lake Tanganyika in present-day Tanzania. In 1977, she set up the Jane Goodall Institute, a nonprofit organization aimed at supporting the research in Gombe as well as conservation and development efforts across Africa.
