Joseph Papalia's Interview

Alexandra Levy: This is Alexandra Levy of the Atomic Heritage Foundation here in New Jersey on June 13, 2016, with Joseph Papalia. My first question is to please say your name and spell it.

Joseph Papalia: Joseph Papalia, P-A-P-A-L-I-A.

Levy: Can you tell us where and when you were born?

Papalia: I was born August 20, 1936, in East Meadow, New York.

Levy: Can you tell us briefly about your life and career, and how you became involved in the 509th Composite Group?

Marvin Wilkening's Interview (1995)

[Many thanks to Thomas Scanlan for recording and donating this interview to the Atomic Heritage Foundation.]

Thomas Scanlan: —Is part of an interview, which I held with Professor Marvin Wilkening at his home on Socorro, New Mexico on July 15, 1995. 

Now, I was reading that you had worked at four different places associated with the Manhattan Project.

Marvin Wilkening: That’s right.

Scanlan: Was your first work with [Enrico] Fermi at Chicago?

Esther Floth's Interview

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.

Lee DuBridge's Interview - Part 2

Lee DuBridge: So, yeah, we thought it was an exciting time to have the AEC [Atomic Energy Commission]. We knew, of course, that they were going ahead with the weapon development, but also they were going to support Brookhaven and other research centers around the country. So, no, I think those of us who were not imminently in the Manhattan District, but aware of it, were quite excited about getting in and finding out more about really what was going on and what the new possibilities were, both in physics and in weapon technology.

Norris Bradbury's Interview - Part 2

Martin Sherwin: Okay, this is the middle of an interview with Norris Bradbury.

Norris Bradbury: The fact that I wasn’t particularly involved in these discussions, of the type which the Federation of Atomic Scientists started—they started here, of course. I suppose I was committed to running a laboratory and trying to get people to stay here, while I was not uncommitted to international control of nuclear weapons, for heaven’s sakes. No one could be.

Louis Hempelmann's Interview - Part 2

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.”

Verna Hobson's Interview - Part 2

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.

Haakon Chevalier's Interview - Part 2

Martin Sherwin: You mentioned a point that others have mentioned that intrigue me: [J. Robert] Oppenheimer’s summer in Corsica. You said that Oppenheimer had once told you that reading [Marcel] Proust’s Memory of Things Past was one of the great experiences of his life.

Haakon Chevalier: Yes.

Sherwin: I have two questions about that. One, could you elaborate on that? Anything that you recall he said and why. The second has to do with whether you know anything else about that summer in Corsica.

Dorothy Ritter's Interview

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?
