One man's obsession, 37 years of his life, 10,000 pages of historical documentary, and the book he authored, are the focus of Prange and Pearl Harbor: A Magnificent Obsession. This program explores the work of Gordon Prange, a University of Maryland professor who researched and wrote, At Dawn We Slept: The Untold History of Pearl Harbor, a book The New York Times called "impossible to forget." His other major works on the war in the Pacific include Tora! Tora! Tora!, which was made into a feature film in 1970. Prange and Pearl Harbor follows Prange's life from chief historian in occupied Japan under General Douglas MacArthur to his professorship at the University of Maryland, through his unceasing journey to publish what is hailed as the definitive book about the attack on Pearl Harbor.
