Napoleon A. Chagnon (/ˈʃæɡnən/ SHAG-nən; born 1938) is an American anthropologist and professor of anthropology at the University of Missouri in Columbia. He is best known for his long-term ethnographic field work among the Yanomamö, a society of indigenous tribal Amazonians, as well as his contributions to evolutionary theory in cultural anthropology, and to the study of warfare. A New York Times reviewer labeled Chagnon the "most controversial anthropologist" in the United States in a New York Times Magazine profile preceding the publication of Chagnon's most recent book, Noble Savages: My Life Among Two Dangerous Tribes—the Yanomamö and the Anthropologists, a scientific memoir. Allegations that he played a role in communal violence and introduced disease prompted his early retirement.^[2]
