American anthropologist Fred Eggan, Harold H. Swift Distinguished Service professor of Anthropology at the University of Chicago, lectured on "Lewis Henry Morgan and Cultural Evolution." Eggan’s application of the principles of British social anthropology in his study of Native American culture aligned him with the pioneering American anthropologist and social theorist Morgan (1818-1881), who first described underlying kinship patterns among Native Americans.

Eggan delivered the Lewis Henry Morgan Lectures at the University of Rochester in 1964, and the lectures were published as The American Indian: Perspectives for the Study of Social Change (1966).
