Douglas Harper is professor of sociology at Duquesne University. He is the author of a number of works of visual ethnography and visual sociology--works that use photography as an innovative adjunct to ethnographic description. His books include Good Company, a much-acclaimed photographic portrait and narrative about tramps on the rails; Working Knowledge: Skill and Community in a Small Shop, a portrait of a mechanic and jack-of-all-trades; Changing Works: Visions of a Lost Agriculture, which explores the social world of dairy farmers in upstate New York; Hong Kong: Migrant Lives, Landscapes, and Journeys, a tour of the city's postcolonial urban landscape; and The Italian Way: Food and Social Life, on the role that food plays in the daily activities of Italians from all walks of life. All five of these books were published by the University of Chicago Press.
