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.

Clarence Larson's Interview

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?

Hans Bethe's Interview (1982) - Part 2

Hans Bethe: The other was M - A - D, MAD [Mutually Assured Destruction], which essentially says that nuclear weapons make sense only as a safeguard against nuclear weapons. As [Wolfgang] Panofsky has said recently, and there is actually an article by him, "It is not a doctrine. It is a fact of life. Nothing else is possible, whatever you might wish.” So I think you should not present it as something really unavoidable, without any movements in the opposite direction.  

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. 

General Kenneth Nichols's Interview - Part 3

General Kenneth Nichols: —found we did not have the authority to satisfy DuPont.

Stephane Groueff: But why did DuPont challenge your authority?

Nichols: Because they had trouble, in World War I, being called munitions makers and investigated after World War I, so they are more conservative than most companies. And they wanted to have in their files copies of our authorities. And what we had, which I have shown you, and that is satisfactory to them.

Groueff: I see.

Peter Lax's Interview

Cindy Kelly: My name is Cindy Kelly with the Atomic Heritage Foundation. It is January 8, 2016, and I am in New York City with Peter Lax. My first question for him is to say his name and spell it.

Peter Lax: Peter Lax, spelled L-A-X.

Kelly: Great, thank you. So I would love to have you talk, just a little bit anyway, about your childhood and your parents.
