Coster-Mullen, John

John Coster-Mullen, a professional photographer, began research in the early 1990s on the two atomic bombs, Little Boy and Fat Man, dropped on Japanese cities during World War II. He created replicas of the bombs, and prepared a manuscript detailing the history of their development and use against Japan. Published in 2004, his book is entitled Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man. Coster-Mullen has attended many reunions of the military personnel who carried out the bombing missions against Japan. He has served as an advisor to the National Atomic Museum and The Children of the Manhattan Project Preservation Association, and has worked with the British Broadcasting Corporation (BBC), which used his book as source material for a documentary on the atomic bombs.
