The Manhattan Project


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.

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.”

Dorothy Ritter's Interview

Cindy Kelly: It is Sunday, May 15, 2016, and we’re in Houston, Texas. I want to start by asking you to tell me your name and then spell it.

Dorothy Ritter: My name is Dorothy Oley Ritter. D-O-R-O-T-H-Y O-L-E-Y R-I-T-T-E-R.

Kelly: All right. Dorothy, why don’t we begin by having you tell us something about your family, when you were born, your childhood?

Louis Hempelmann Interview - Part 1

Martin Sherwin: Martin Sherwin, I am about to interview Dr. Hempelmann at Strong Memorial Hospital.

You know, simply from all of the Los Alamos records, but who told me you were at Strong? That was, I think, Dorothy McKibbin.

Louis Hempelmann:  Oh yeah.

Sherwin: No, she confirmed it. She said you were coming out to Santa Fe.

Hempelmann: Yeah.

Nancy Greenewalt Frederick's Interview (2006)

Nancy Greenewalt Frederick: My father, Crawford Greenewalt, was the only child of Dr. Frank Lindsay Greenewalt and Mary Hallock Greenewalt. Dr. Greenewalt was a physician at Gerard College in Philadelphia, and my father grew up there most of his young life. He went to a German school, what we would call a preschool, run by German monks when he was a child. He says he spoke German before he spoke English. But when he was grown up he could do some German, but he couldn’t speak it.

Harry Allen and Robert Van Gemert's Interview

Harry Allen: Mr. Wilson and company set us up a purchase request for a barber chair, because they couldn’t get off work in time to get their hair done.

Robert Van Gemert:  There was only one man cutting hair, I think, up there.

Allen: The barber service was extremely limited, and we just happen to know where there was an old barber chair down in the old engineers’ warehouse. So we sent the truck driver down, and we delivered one barber chair down to the cyclotron building. 

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?
