Leslie Groves

"At the time I was brought into the picture, research on the uses of atomic energy had been going on at a gradually accelerating pace since January, 1939, when Lise Meitner explained that the uranium atom could be split. The discovery opened up two divergent paths for its exploitation. Most physical scientsts realized that nuclear energy, derived from the splitting, or fissioning, of the atom, might be used either to generate power for peaceful purposes or to generate super-weapons. In general, however, it was the scientists who were personally acquainted with Hitlers New Order who first became most interested in the possible military uses of atomic energy and its effect on the existing balance of political power."

"I think the data that went out in the case of the Rosenbergs was of minor value. I would never say that publicly. Again that is something while it is not secret, I think should be kept very quiet, because irrespective of the value of that in the overall picture, the Rosenbergs deserved to hang, and I would not like to see anything that would make people say General Groves thinks they didn’t do much damage after all."

"At present the best defense against the atomic bomb is to not be there when it goes off."

"For three critical years he directed the most awesome project in the history of mankind. He was a constant source of amazement . . . He had the deep respect and admiration of his staff for his ability to organize and get things done."

"He had a fatal weakness for good men."

"Hes a genius. A real genius. While Lawrence is very bright, hes not a genius, just a good hard worker. Why, Oppenheimer knows about everything. He can talk to you about anything you bring up. Well, not exactly. I guess there are a few things he doesnt know about. He doesnt know anything about sports."

"First, General Groves is the biggest S.O.B. I have ever worked for. He is most demanding. He is most critical. He is always a driver, never a praiser. He is abrasive and sarcastic. He disregards all normal organizational channels. He is extremely intelligent. He has the guts to make timely, difficult decisions. He is the most egotistical man I know. He knows he is right and so sticks by his decision. He abounds with energy and expects everyone to work as hard or even harder than he does. Although he gave me great responsibility and adequate authority to carry out his mission-type orders, he constantly meddled with my subordinates. However, to compensate for that he had a small staff, which meant that we were not subject to the usual staff-type heckling. He ruthlessly protected the overall project from other government agency interference, which made my task easier. He seldom accepted other agency cooperation and then only on his own terms. During the war and since I have had the opportunity to meet many of our most outstanding leaders in the Army, Navy and Air Force as well as many of our outstanding scientific, engineering and industrial leaders. And in summary, if I had to do my part of the atomic bomb project over again and had the privilege of picking my boss I would pick General Groves."
