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.
Ted Taylor: I think Carson Mark is the most valuable resource to talk to about what happened in those days at Los Alamos. At Livermore, [Edward] Teller, certainly.
Richard Rhodes: Teller won't talk to me, I'm afraid. He’s decided I’m the enemy.
Reed Srere: Hi, I am Reed Srere – R-e-e-d S-r-e-r-e. I am recording this oral history for the Atomic Heritage Foundation on June 3  in Washington, DC. Please state your name.
David Fox: I am David Fox. I live in Providence, Rhode Island. My father was a physicist on the Manhattan Project in Manhattan. That is why I am here.
Srere: Please tell us your place and date of birth.
[Thanks to Ronald K. Smeltzer for donating the record "To Fermi with Love" to the Atomic Heritage Foundation.]
Norman Brown: My name is Norman L. Brown. Brown is spelled as Brown is usually spelled, without an E.
Cindy Kelly: Great, okay. Why don’t you start by telling us how you became part of the Manhattan Project?
Stephane Groueff: Start from the beginning and if you can give me in a few words the history of how it started, who actually came into contract, and how?
[Audio distortion occurs throughout the interview.]
Stephane Groueff: Recording interview with Mr. Leon Love at Oak Ridge July 15, 1963. Mr. Love works with Y-12.
Would you mind repeating sort of some of the characteristics of Y-12, some of the figures? For instance, how many buildings? How many magnets? How many Alpha [calutrons] and Beta [calutrons]? How many units in each?
Leon Love: There were five buildings containing the output separators, and there were nine tracks total in these five buildings.
Stephane Groueff: Now it is recording Dr. Langsdorf. If you can tell me in a few words how you got connected with the project and where you came from.
Alexander Langsdorf: Oh, in the first place, as soon as I got my PhD at MIT, I went out to Berkeley as a national research fellow and started to work in Ernest Lawrence’s lab doing nuclear physics, which was a brand new field then, just opening up in 1938.
Cindy Kelly: I'm Cindy Kelly. This is Wednesday, June 24th, 2015, and I'm in Cambridge Massachusetts with Peter Gailson. My first question for you is to tell me your name and spell it.
Peter Galison: My name is Peter Gailson, G-A-L-I-S-O-N. I'm a professor here at Harvard, Physics, a history of science.
Groueff: General Nichols, Part 2.
Nichols: But Dobie [Percival Keith] came back immediately, or shortly thereafter, with the suggestion we build more gaseous diffusion base plants, and that was why we built the K-27 plant.
Groueff: A base?
