British primatologist Jane Goodall (1934–) is famous for her studies of chimpanzees in Tanzania. She began her career as a secretary in Nairobi, Kenya, for anthropologist Louis B. Leakey (1903–1972); she later spent her time studying chimpanzees. After more than forty years of research, Goodall showed that chimpanzees could make and use tools (a behavior previously attributed only to humans). She was also able to distinguish the individual personalities among the chimpanzees she studied. She currently continues her work through the Jane Goodall Institute.
