"In this well-crafted, impressively researched biography, Michael Leroy Oberg has told Eleazer Williams's complete life story and told it well. In Oberg's hands, Williams was a serial liar, and he became a 'professional Indian' in order to make a living at a time of shrinking options for Indians. Professional Indian will be the authoritative account of this significant figure in Iroquois history."--David J. Silverman, George Washington University.
