John P. Langellier received both a BA and MA from the University of San Diego in history/historical archeology with an emphasis on the Spanish borderlands and American West. He subsequently obtained his PhD from Kansas State University with an emphasis on military history. Thereafter, his public history career of over four decades included postings as a historian, museum and archives director, and instructor. Langellier is the author of more than twenty books, including Scouting with the Buffalo Soldiers: Lieutenant Powhatan Clarke, Frederic Remington, and the Tenth U.S. Cavalry in the Southwest (UNT Press); Fighting for Uncle Sam: Buffalo Soldiers in the Frontier Army; Bluecoats: The U.S. Army in the West, 1848–1897; Longknives: The U.S. Cavalry and Other Mounted Forces, 1848–1942; and Custer: The Man, the Myth, the Movies.
""Langellier integrates historical trends outside of the presidio and a broader historical context into the 'close focus' story of the development, events, people, and physical history of the place itself. I am particularly impressed by the depth of research. The use of primary sources is extraordinary and testifies to the author's command of the subject. The significance of the presidio lies not only in the structure/landscape or the events that happened there but also in the tenants that it housed: This is the place where Bobby Kennedy was shot, where Enrico Caruso sang, where a historic treaty was signed, and where Harry met Sally.""—Stephen A. Haller, author of Post and Park: A Brief Illustrated History of the Presidio of San Francisco and Last Word in Airfields: San Francisco's Crissy Field
