This book was written, as stated on the cover page, By Leslie R. Groves, Lieutenant General, U.S. Army, Retired. I’ve read several books about the Manhattan Project, and I would put this on at the top of the list to someone who has just developed an interest in the subject. It describes in no uncertain terms the complexity and difficulty of what was being sought and the remarkable achievements that resulted. To General Groves’ credit, he dedicates the book, “To the men and women of the Manhattan Project, and to all those who aided them in their yet unparalleled accomplishment.” I was impressed by the number of times Groves wrote about something going wrong because of something he had done. He shied away from blaming others for problems and gave credit to those who suggested some insight or approach that he had not considered. My “personal review” of the book that I prepared for use in a new book I’m researching about the history of the Rocky Flats Nuclear Weapons Plant covers twenty-three pages. I promise to impose a much shorter version in this review.
Groves was in charge constructing the Pentagon when he was told he had been selected by the Secretary of War for an important project, and that his selection had been approved by President Roosevelt. I was surprised that Groves knew about what he called “…the atomic development program…,” and responded unenthusiastically, “Oh, that thing.” He met with his commanding General who told him, “The basic research and development are done. You just have to take the rough designs, put them in final shape, build some plants and organize an operating force and your job will be finished and the war will be over.” Groves admits in his book that it took weeks before he had a comprehension of, “…how overoptimistic an outlook he had presented.”
Groves describes the research by physicists that led some to conclude an atomic bomb was possible. Lise Meitner explained to Otto Hahn that the results of his research in Germany indicated the uranium atom could be split and that the resulting fission (a term developed by Meitner and her nephew) would release enormous amounts of energy. The genesis of the Manhattan Project was initiated by scientists Hitler drove out of Germany. Many came to America, and they feared what would happen if the Germans were the first to develop the bomb. One of the problems they faced was that the “…American-born scientists, in the main, did not have so acute and appreciation of the danger…” The process that resulted in Franklin Roosevelt approving research is described in numerous sources, but the Groves account is, in my estimation, adequately complete and to the point.
