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.
Stephane Groueff: Interview with Dr. Clarence Larson—L-A-R-S-O-N—head of the Union Carbide’s operations at Oak Ridge, a chemist. Dr. Larson was connected with the electromagnetic separation process during the war, and he was a personal friend of Dr. Lawrence [Ernest O. Lawrence]. He’s married to the daughter of Dr. Stafford Warren, who was also with the project. You came in 1942?
Dr. Clarence Larson: Yes.
Groueff: From where?
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.
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?
Sherwin: Who else was there in that group?
Stephane Groueff: [Enrico] Fermi had the characteristics of a real genius.
Colonel Franklin Matthias: Almost every time you would get in contact with him, something would come up that was impressive. Physically, he was a small man, unimpressive person, but he grew real large when he started talking about things he knew.
Groueff: Was he a friendly person?
Matthias: Yes, warm; very warm, very friendly, a real nice person.
Isabella Karle: Isabella Karle. I-S-A-B-E-L-L-A K-A-R-L-E
Cindy Kelly: Terrific. Could you tell us how you happened to become part of the Manhattan Project?
Ralph Lapp: I am Ralph Lapp, L-A-P-P. I am a physicist, nuclear physicist, an author, and a consultant. I have engaged in finance and technology.
Interviewer: Great. What can you tell us about your role in the Manhattan Project?
Martin Sherwin: This is Martin Sherwin. I am on my way to interview Professor Robert Christy in his office at 423 Downs on the Caltech Campus in Pasadena, California, March 30th, 1983.
You were a student of his?
Robert Christy: I was a graduate student of [J. Robert] Oppenheimer’s from the fall of 1937 until the spring of 1941 when I got my degree, my PhD degree in theoretical physics in Berkeley.
Sherwin: What did you do your dissertation on?
Stephane Groueff: It is working. Mr. Stapleton, you were with security during the Hanford period, or you were already here with security in DuPont in Wilmington?
Newton Stapleton: I was in the security prior to Hanford. At the beginning of the war, DuPont got involved in building a plant for the French and British down at Memphis, Tennessee. Then as our country became more involved, we got involved in trying to please or satisfy the government from the Air Force, the Army, the Navy, the Coast Guard and everything.
Martin Sherwin: Today is March 30, 1983. I am at the CalTech campus and I am going to interview President Emeritus Lee DuBridge at his home in Pasadena.
Lee DuBridge: But we were on many things together and so we saw a good deal of each other. I visited him [J. Robert Oppenheimer] at his home in Princeton a number of times. We had meetings there and we would drop in for social visits and so on.
Sherwin: I would like to sort of try to bore in on some of the points.
