Donald Ross: My name is Donald Ross, and I am about to begin my eightieth year on this planet. I was born in Kenosha, Wisconsin, and I left there with my parents at an early age. We moved to the southern tip of Texas, and had a little farm not too far from Edinburg, Texas, where I grew up.
Crawford Greenewalt: Crawford Greenewalt. I’m named after my father, Crawford Hallock Greenewalt. The last name, Greenewalt, is spelled G-R-E-E-N-E-W-A-L-T. But in early years in the country, the Greenewalt’s spelled their name various ways. The present spelling may go back several generations.
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: —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.
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?
Jerome Karle: My name is Jerome Karle. And it is J-E-R-O-M-E K-A-R-L-E.
Cindy Kelly: Great. Dr. Karle, can you tell me about what you were doing in the early 1940s and how you happened to become part of the Manhattan Project?
Karle: Well, I had just finished my work in 1943, for my graduation on my degree.
Isabella Karle: Your PhD.
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.
Stephane Groueff: Mr. Hobbs, part two. So to go now to how you were contacted for the Manhattan Project.
J.C. Hobbs: You see, [Ludwig] Skog was one in the group and had me in on –
Groueff: And [William Francis] Gibbs.
