Edwin McMillan: Ladies and gentlemen, I would like to start with two remarks. First, this is going to be a personal story, so if I use the first person singular, this is not pure egotism, it is simply the fact that that’s the part that I know best. Second remark is, the difficulty of establishing facts at such a late date, even of important things. During the Manhattan Project, of course, there was security impressed upon everyone, so very few people kept any notes.
Owen Gingerich: This is an interview between Owen Gingerich and Robert Wilson. You use your middle initial. It’s Robert R.?
Robert Wilson: Yes, usually.
Gingerich: Robert R. Wilson, who is a builder of high energy accelerators and who was one of the physicists at Los Alamos. We are speaking today in Philadelphia, where we both happen to be for the American Philosophical Society. It’s April 22. No, it’s Shakespeare’s birthday. It’s April 23. That’s the documentation for the day.
Cindy Kelly: Okay, I am Cindy Kelly, Atomic Heritage Foundation. It’s August 9, 2016 and we are in Berkeley, California. I have with me Esther Floth. Our first question I want to ask is for her to tell us your name and to spell it.
Esther Floth: My name is Esther Marie Green Floth. It’s E-S-T-H-E-R; last name F as in “friendly,” L-O-T-H.
Kelly: Great. Esther, tell us something about your beginnings. When were you born and where were you born, and something about your childhood.
Louis Hempelmann: He [J. Robert Oppenheimer] just told me what the situation was. He did not ask me, which is the same thing when he got sick because I was in the radiology department here and I knew something about it. He would call me up, tell me what he had done, and then say “What do you think of it?” By that time, the only thing I could say was, “That was fine.”
Martin Sherwin: Was there a lot of effort to trying to figure out the psychology that the people who were sitting in judgement [at J. Robert Oppenheimer’s security hearing] would have? That “They will probably be thinking this, so therefore we should do that?” Do you recall any of that?
Verna Hobson: No. I remember that after the first—they came back, I suppose, the weekend in the middle of the hearings. I think they had a few days, and then they came back, and then they went to Washington again for the rest of it.
Jean Bacher: Ruth Valentine said, “I shall take Ruth [Tolman]’s desk.” She always saved letters. She had marvelous long letters from Robert, you know, especially at the time of the hearings. I knew they were just terribly close and shared a great deal. On the drawer of the desk, she’d said, “Destroy these.”
Martin Sherwin: You saw it happen?
Bacher: I didn’t see her burn it, because at that time we still burned and they just threw them out in the burner in the back yard.
Martin Sherwin: How much were the dues [to the Communist Party]?
David Hawkins: God, I don’t remember. Not very much, or I wouldn’t have been able to afford them.
Sherwin: Two bucks, five bucks?
Hawkins: Yeah, something like that.
Sherwin: A month?
Cindy Kelly: It is Sunday, May 15, 2016, and we’re in Houston, Texas. I want to start by asking you to tell me your name and then spell it.
Dorothy Ritter: My name is Dorothy Oley Ritter. D-O-R-O-T-H-Y O-L-E-Y R-I-T-T-E-R.
Kelly: All right. Dorothy, why don’t we begin by having you tell us something about your family, when you were born, your childhood?
Martin Sherwin: This is Martin Sherwin, I’m on my way to interview William Fowler at Caltech in Pasadena. Today is March 29, 1983.
Martin Sherwin: At the Stanhope Hotel in New York, June 15th, 1979.
David Bohm: I met him in about 1941. I went to Caltech to do graduate work, and I wasn’t very satisfied there. It was much too limited technically.
Sherwin: Where did you do your undergraduate work?
