Irven DeVore (1934–2014), a professor at Harvard over five decades, was a pioneer in field studies of living primates and extant hunter-gatherers. His research with Sherwood Washburn on baboon behavior was largely responsible for establishing primatology as a part of anthropology. Later projects on the !Kung San (Bushmen) of Botswana and the people of the Ituri rainforest pioneered multidisciplinary research on living hunter-gatherers. He was a prominent supporter of sociobiology from its beginnings.
