C. L. Sonnichsen (Ph.D., Harvard) has been investigating and writing about his major interests—the history, literature, and folklore of the Southwest—since his arrival in the area in 1931 to teach English at what has since become the University of Texas at El Paso. His published works of Southwestern history and fiction include Cowboys and Cattle Kings, Ten Texas Feuds, Billy King’s Tombstone, and Alias Billy the Kid. A retired professor, Sonnichsen is editor of the Journal of Arizona History and director of publications for the Arizona Historical Society.
