Charles Warren Hollister (November 2, 1930 – September 14, 1997) was an American author and historian. He was one of the founding members of the University of California Santa Barbara history department.[1] He specialized in English medieval history, especially studies that emphasized the interrelationship of England within the Anglo-Norman realm and the development of administrative kingship. His colleague Jeffrey Burton Russell called Hollister "one of the best medieval generalists in the world."[2]
