Mary Leakey, one of the world's most renowned hunters of early human fossils, died in Nairobi on December 9, 1996, at the age of 83. Crowning triumphs of her long career included such finds as the 1972 discovery (with Louis, her husband and collaborator) of 1.75-million-year-old remains from Homo habilis at Olduvai Gorge and the 1978 discovery of 3.6-million-year-old footprints at Laetoli, both in Tanzania.
This profile of Dr. Leakey, written by former news editor Marguerite Holloway, originally appeared in the October 1994 issue of Scientific American
