Julie Melton's Interview

Cindy Kelly: I’m Cindy Kelly. This is Santa Fe, New Mexico, Wednesday, October 12, 2016. I have with me Julie Melton. My first question for Julie is to say her name and spell it.

Julie Melton: I’ve been widowed twice, so I’ve had a lot of last names, but my maiden name was Hawkins. My father was at Los Alamos. Now my name is Melton, Julie Melton. Just to make it complicated, I’ve written books on democratization in the developing world, and I used my pen name Fisher for that. So it does get complicated.

Louis Hempelmann's Interview - Part 4

Louis Hempelmann:  I do not think the people who came later were ever as close as the people who were there at the beginning.

Martin Sherwin: Did most of the people who came later, were they junior people? That is, younger? [Enrico] Fermi came later.

Hempelmann: [George] Kistiakowsky came later.

Sherwin: He did? When you say “earlier” and “later,” what dates are you talking about?

Louis Hempelmann's Interview - Part 3

Martin Sherwin: What was the set-up at Los Alamos, in terms of your relationship to the director [J. Robert Oppenheimer] and how you operated?

Louis Hempelmann:  I was working directly under him. I started out with my wife as a half-time secretary, and the technician I brought with me from St. Louis, and Kitty worked for me.

Sherwin: What did Kitty do for you?

Hempelmann: Did blood counts.

Sherwin: Was she a good technician?

Verna Hobson's Interview - Part 3

Hobson: One thing that used to happen to particularly interesting and sensitive papers was that Kitty would take them home, and then they would get lost. Lots of things went that way, including a whole batch of interesting tapes. It was very embarrassing because we had promised [Dean] Acheson that only one copy would be made, and we made two copies and we kept them. When he found out he was quite angry.

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.

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.

Jean Bacher's Interview

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.
