Claude Eatherly gave the signal for the dropping of the bomb at Hiroshima. ... He was not told what the bomb would do and was utterly horrified when he discovered the consequences of his act. He devoted himself throughout many years to various kinds of civil disobedience with a view to calling attention to the atrocity of nuclear weapons and to expiating the sense of guilt which, if he did not act, would weigh him down. The Authorities decided that he was to be considered mad, and a board of remarkably conformist psychiatrists endorsed that official view. Eatherly was repentant and certified; Truman was unrepentant and uncertified.
