Richard Rhodes: You said [Richard] Courant’s work added realism? Ted Taylor: Yeah. Rhodes: How so? Taylor: By going over various tricks for dealing with the discontinuities, the singularities in the hydrodynamics. I had the impression that he was very helpful to people like Bob Richtmyer. I don’t know that Richard himself came up with anything […]

[Thanks to Ronald K. Smeltzer for donating the record “To Fermi with Love” to the Atomic Heritage Foundation.] Narrator: Only thirty-one months had passed since Stagg Field. What followed the Trinity event is now history. Within forty-eight days of its demonstration near Alamogordo, the atomic bomb formally brought World War II to an abrupt end on […]

Richard Rhodes: How did you get involved in the program? Marshall Rosenbluth: Well, you can probably guess. I’ve already told you that I was a student of [Edward] Teller’s. I was in the Navy during the war and then went back to the University of Chicago where my parents were living, to graduate school, and […]

Robert Lamphere: One of the British newspapers speculated about allowing the FBI into see this guy [Klaus Fuchs], because we might actually use the third degree against him – which we thought was funny as hell. But right off the bat, he wasn’t sure he wanted to tell me anything, because of what we filed […]

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. Taylor: Herb York I think is anxious for the story to be told correctly. […]

[Thanks to Ronald K. Smeltzer for donating the record “To Fermi with Love” to the Atomic Heritage Foundation.] Narrator: Finally, the decision was made: build the pile in the west stands. The facilities under Stagg Field included the usual locker room, showers, and four handball or racquets courts. The heavy graphite material began to roll in […]

[Thanks to Ronald K. Smeltzer for donating the record “To Fermi with Love” to the Atomic Heritage Foundation.] Narrator: It was a major emotional decision for Mrs. Fermi, causing her great pain. She had been born in Rome, always lived there. Her relatives and friends were there. She felt she belonged to Rome, but in May […]

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? Nichols: Yeah, a base. See, more base, to where he then optimized. How do you optimize the K-25 system with the […]

Narrator: Apparently aloof from the rest of World War II, the solitary 509th, still unaware of its own purpose, carries on its puzzling training schedule. Their orders: practice runs to nearby islands. Then their own private missions to Japan, always above thirty thousand feet, always alone or in threes, always to drop just one bomb. Each […]

Interviewer: At two forty-five in the morning of August 6, 1945, the B-29 Enola Gay took off from North field on Tinian. Aboard the plane were thirteen men a thing called “the Gimmick.” Some fourteen hundred miles and six hours later, the Enola Gay reached her appointment with history. The time was fifteen minutes and seventeen […]
