California is a contentious arena for the study of the Native American past. Some critics say genocide characterized the early conduct of Indian affairs in the state; others say humanitarian concerns. Robert F. Heizer, in the former camp, has compiled a damning collection of contemporaneous accounts that will provoke students of California history to look deeply into the state's record of race relations and to question bland generalizations about the adventuresome days of the Gold Rush. Robert F. Heizer's many works include the classic The Other Californians: Prejudice and Discrimination under Spain, Mexico, and the United States to 1920 (1971), written with Alan Almquist. In his introduction, Albert L. Hurtado sets the documents in historical context and considers Heizer's influence on scholarship as well as the advances made since his death. A professor of history at Arizona State University, Hurtado is the author of Indian Survival on the California Frontier.
