This first full-scale biography of Edward Sapir (1884–1939) does justice to the life and ideas of the most distinguished linguist of Boasian anthropology, who contributed substantially to the professionalization of linguistics as an independent discipline. Sapir was the first to apply comparative Indo-European methods to the study of American Indian languages, pursuing fieldwork on more than twenty of them. His theoretical work on the relationship between the individual personality and culture remains a major part of culture theory in anthropology, as does his insistence on the symbolic nature of culture and the importance of culture as understood and articulated by its members. The first professional anthropologist in Canada and teacher of a whole generation of North American linguists and anthropologists at Chicago and Yale, Sapir also wrote poetry and literary criticism. He insisted on the humanistic nature of anthropology and was the most articulate spokesman for the interdisciplinary social science of the late 1920s and 1930s. All the richness and diversity of Sapir’s relatively short life are conveyed by Regna Darnell in an engrossing narrative that combines profound knowledge of her subject with historical reconstruction.
