The Manhattan Project

Seth Neddermeyer

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.

Robert Bacher's Interview - Part 2

Robert Bacher: I presented this [the discovery of the neutron] in the seminar and there were a good many questions. Some people were skeptical. I convinced Ed Condon almost immediately. In fact, within the week we had written a note together on the spin of the neutron because you could work it out. This part of it fit into the things of nuclear spins, hyperfine structure, nuclear moments, and so on. A good many other people came around to it. I think more than half the people were convinced at that time.

Sir Rudolf Peierls's Interview

Martin Sherwin: This is Martin Sherwin. I'll be interviewing Sir Rudolf Peierls at the State University of New York at Stony Brook. Today's date is June 6th, 1979. 

You first met [J.Robert] Oppenheimer in Zurich in 1929?

Rudolf Peierls: Right, yes.

Sherwin: At that time, I think you mentioned you were working with [Wolfgang] Pauli's group?

Peierls: Yeah.

Sherwin: Who else was there in that group?

Charles Critchfield's Interview

Charles Critchfield: Is that your book, by the way?

Richard Rhodes: Yes.

CritchfieldMaking of the Atomic Bomb?

Rhodes: Yes.

Critchfield: I’ve always heard it, Making of the Bomb. No, I didn’t know it was your book. Rubby Sherr sent me that, and he also sent me excerpts from two or three other books on the bomb. Rubby was my main man in my group for making the Initiator.

Charles Critchfield

Charles Critchfield was a mathematical physicist assigned to work on the development of gun-type fission weapons, and eventually implosion-type weapons, at Los Alamos. He returned to Los Alamos in 1952 to work on the development of the hydrogen bomb.

Rex Edward Keller's Interview

Alexandra Levy: All right. We are here on April 23, 2015 with Mr. Rex Edward Keller. So first, can you please say your name and spell it.

Rex Keller: Oh, Rex Edward Keller, R-E-X E-D-W-A-R-D, Keller, K-E-L-L-E-R.

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

Keller: I was born in Saxton, Missouri, October 10, 1923.

Levy: And you grew up in Missouri?

Keller: Yes, yes, in Dexter, Missouri.

John Manley's Interview (1965) - Part 1

Stephane Groueff: Yes, Dr. Manley, from the beginning. Then I’ll start asking questions.

John Manley: Alright, fine. I guess the first relevant business is the fact that I went to Columbia in ‘34. I was sort of on the fringe. I worked mostly with [Isidor] Rabi for the first couple of years.

Groueff: You are a chemist?

Manley: No, I’m a physicist.

Groueff: Physicist?
