Book excerpt: A Northern Cheyenne Album presents a rare series of never-before-published photographs that document the lives of tribal people on the reservation during the early twentieth-century—a period of rapid change. Reservation physician and expert photographer Thomas B. Marquis captured Northern Cheyenne life in numerous images taken from 1926 to 1935. After 1960, former tribal president John Woodenlegs and others interviewed tribal elders and, drawing on tape recordings, composed the photos' lively captions. Margot Liberty, editor of this volume, has added her own descriptions, filling in details of Northern Cheyenne culture and history from a scholar's viewpoint.
