Mary Leakey (1913-1996) was an anthopologist and archaeologist who searched for the roots of humankind in Africa with her husband, Louis Leakey. Together, they made the famous discovery of remains of a Homo habilis in 1972. Although she never attended a university except to watch the occasional lecture, she made several notable anthropological discoveries in her lifetime, including a whole new group of hominids, Australopithecus boisei, and 2-million-year-old Oldowan stone tools.
