Roger Rohrbacher was born in St. Paul, Minnesota on March 11, 1920. He graduated from Macalester College in 1942 with a degree in chemistry and physics. Rohrbacher joined the Manhattan Project and was sent to Hanford in early 1944. He worked as an instrument engineer at the B Reactor. Rohrbacher was tasked with measurign neutron flow and temperature pressure and radiation monitoring.
Corporate Involvement in the Manhattan Project
Cindy Kelly: I’m Cindy Kelly, Atomic Heritage Foundation, and it’s Friday, May 15, 2015, and I’m in Middlebury, Vermont, with Irwin P. Sharpe. And, my first question for him is to tell us your name and spell it.
Irwin Sharpe: Oh, I know that. Okay. It’s Irwin, I-r-w-i-n, initial P, Sharpe, S-h-a-r-p-e.
Irwin P. Sharpe was born in 1921. He was recruited for the Manhattan Project by his employer, General Electric, after he graduated from the University of Michigan with a degree in engineering in 1942. His work took place in the Woolworth Building in Manhattan, where he played a key role in developing pumps and seals to transport gas and oil.
Mary Kalbert: My name is Mary Kalbert and I am in Friday Harbor, Washington, interviewing Gordon Steele on June 16, 2014 for the Atomic Heritage Foundation Manhattan Voices Project. Gordon?
Gordon Steele: My name is Gordon, and you want me to spell my name?
Kalbert: Please spell your name for me.
Steele: Gordon. G-O-R-D-O-N. Steele. S-T-E-E-L-E.
Stephane Groueff: Now, we could start with a letter of [Enrico] Fermi and a letter of [John] Dunning, because the way Dunning explained the thing that he had the idea that uranium-235 was—
Alfred Nier: The one that was responsible, yes.
Stephane Groueff: Hello, Dr. Wigner?
Eugene Wigner: Yes.
Groueff: Good morning sir. I am calling from New York. I am the correspondent of “Paris Match” magazine. My name is Groueff.
Groueff: Groueff, G-R-O-U-E-F-F.
Wigner: I see, Mr. Groueff.
Freeman Dyson: I’m Freeman Dyson, F-R-E-E-M-A-N D-Y-S-O-N, retired professor of physics at the Institute for Advanced Study in Princeton.
Cynthia Kelly: Why don’t we start with your experience in World War II? Maybe you could tell us what your role was.
Marge Shipley: As for housing, men would come too, because they would feel that they would get sent for their wives.
Shirely Tawse: What would you do then, take it up with the Tennessee Eastman?
Shipley: I would take it up with Eastman and do what I could. I’d quiet them down if I could. If I saw no reason for their squawks and thought I couldn’t do any better, I’d try to be as diplomatic as I could. I never was cross with anyone.
Stephane Groueff: Mr. Gary, what was your job at that time here?
Tom Gary: Head of the design division. The engineering department had five divisions: design, construction, engineering services—that’s a division of consultants and they have young engineer’s resident on many of the DuPont plants. The fourth one was control, which is to take care of the payroll and all of that stuff, sort of like Ashton General in the army. And then the fifth one was the engineering research division. I headed the design division.
