Clark Wissler (1870-1947) was an American anthropologist and a specialist in North American ethnography, focusing on the Indians of the Plains. He was the first anthropologist to perceive the normative aspect of culture, to define it as learned behavior, and to describe it as a complex of ideas, all characteristics of culture that are today generally accepted. Alice Beck Kehoe is Professor Emerita of Anthropology at Marquette University. She is the author of many books, including Controversies in Archaeology; The Ghost Dance: Ethnohistory and Revitalization, Second Edition; and North American Indians: A Comprehensive Account, Third Edition. Stewart E. Miller (1950-2008) was a Blackfeet tribal member who worked at the Tribal Historic Preservation Office. He collaborated with Kehoe, providing much of the research material and ensuring that the text reflected Blackfoot culture correctly, until he passed away suddenly in 2008.
