Daniel_A._McGovern
Lieutenant colonel Daniel A. McGovern was the first American to film the aftermath of the atomic bombings of Hiroshima and Nagasaki.[1] The United States Army Air Forces officer, who was both a combat cameraman and a specialist in assessing the effective of bomb damage, made the films in September 1945. The evidence that McGovern collected from Japan was shown to J. Robert Oppenheimer and the team which created the weapons. Concerned that the US government might censor the images, McGovern kept secret original prints. He made these prints available to US congress in 1967.[1]
McGovern was personal photographer to US president Franklin D. Roosevelt. [2]
