James Lockhart (born April 8, 1933 - January 17, 2014) was a U.S. historian of colonial Spanish America, especially the Nahua people and Nahuatl language. Born in Huntington, West Virginia, Lockhart attended West Virginia University (BA, 1956) and the University of Wisconsin–Madison (MA, 1962; PhD, 1967). Late in life, Lockhart wrote a short, candid memoir. He joined the US Army and was posted to Germany, working in "a low-level intelligence agency," translating letters from East Germany. Returning to the US, he entered the graduate program at University of Wisconsin, where he pursued his doctorate in the social history of conquest-era Peru. His dissertation, published in 1968 as Spanish Peru, 1531-1560 was a path breaking approach to this early period. Less interested in the complicated political events of the era, he focused on the formation of Spanish colonial society in the midst of Spanish war with the indigenous and internecine struggles between factions of conquerors. With separate chapters on different social groups, including Africans and indigenous brought into the Spanish sphere, and an important chapter on women of the conquest era, his work shifted the understanding of that era. His main source for the people and processes of this early period were notarial documents, often property transfers and other types of legal agreements, which gave insight into the formation and function of Spanish colonial society. The work is now a classic and was published in a second, revised edition in 1994. While researching Spanish Peru, he compiled information on the Spaniards who received a share of the ransom of the Inca Atahualpa, extracted at Cajamarca. The Men of Cajamarca has both individual biographies of those who shared in the treasure, as well as a thorough analysis of the general social patterns of those conquerors. Both Spanish Peru and The Men of Cajamarca have been published in Spanish translation. He began to do research on colonial Mexico while at University of Texas, looking both at the socioeconomic patterns there and began learning Nahuatl. Fruits of these new interests were the publication of the anthology Provinces of Early Mexico: Variants of Spanish American Regional Evolution (edited with Ida Altman) and Nahuatl in the Middle Years: Language Contact Phenomena in Texts of the Colonial Period (with linguist Frances Karttunen). He moved to University of California, Los Angeles, where he spent the bulk of his teaching career 1972–1994, retiring early and continuing to collaborate with
