Felix DePaula's Interview (2008)

[Thanks to David Schiferl and Willie Atencio for recording this interview and providing a copy to the Atomic Heritage Foundation.]

David Schiferl: Tell us how you got here.

Felix DePaula: Well, let me start with being inducted into the service in 1944, October of ’44, into the Corps of Engineers at Fort Dix, New Jersey. Then from there, I was sent to Fort Belvoir, Virginia, and I spent a couple of months in the wintertime at Fort Belvoir, Virginia.

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?

Edwin McMillan's Lecture

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.

Edwin McMillan

Edwin and Elsie McMillan were among the first people to arrive at Los Alamos. Edwin, who would go on to win the Nobel Prize in Chemistry, was involved in the initial selection of Los Alamos. In this lecture, Edwin describes visiting Jemez Springs and Los Alamos when he, Oppenheimer, and General Groves were deciding on the site for the weapons laboratory. McMillan also discusses his involvement in the implosion research, the gun program, and recruiting scientists including Richard Feynman to the project. 

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?

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.”
