Goodall died of natural causes, the Jane Goodall Institute said in a social media post. There, an encounter with famed anthropologist and paleontologist Dr. Louis Leakey and his wife, archaeologist Mary Leakey, set her on course to work with primates. Under Leakey, Goodall set up the Gombe Stream Chimpanzee Reserve, later renamed the Gombe Stream Research Centre, near Lake Tanganyika in present-day Tanzania. “Now we must redefine tool, redefine man, or accept chimpanzees as humans,” Leakey said of the discovery. 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.
