Stephane Groueff: Dr. Raymond Grills, DuPont, Wilmington.
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.
Gerhart Friedlander: My name is Gerhart Friedlander.
Interviewer: What was your role in the Manhattan Project?
Friedlander: I got into the Manhattan Project very early; in fact, before there was an official Manhattan Project. I was a graduate student at Berkeley at the University of California. My thesis advisor was Glenn Seaborg, who later on got a Nobel Prize and became chairman of the Atomic Energy Commission, but at that time he was just a new instructor and I was his first graduate student.
Ernest Tremmel: I'm Ernie Tremmel.
I graduated from the University of Wisconsin in civil engineering, and I went to work for the Corps of Engineers in St. Louis. One of my bosses was a Captain Powell who, after I was in St. Louis two years, got transferred to a secret project he was going to work on called the Manhattan Project Corps of Engineers.
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?
Martin Sherwin: This morning I am making arrangements to interview Norris Bradbury in Los Alamos, New Mexico. January 10, 1985.
How would you characterize the major problems that [J. Robert] Oppenheimer had when he first got the job as the administrator for Los Alamos? Or at least, when you came on?
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.
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.
The Purdue University Physics Department operated a cyclotron during the early part of the war, conducting important nuclear research. Many of the scientists working on the project were transferred to Los Alamos to continue work on the Manhattan Project.
