Louis Rosen, a native New Yorker and the son of Polish immigrants, was personally selected to work on the Manhattan project in Los Alamos while a graduate student in physics. Once in Los Alamos, Rosen was assigned to Edwin McMillan’s group, where he worked on implosion technology. Rosen remained in Los Alamos after the war ended and was considered the father of the Los Alamos Meson Physics Facility.

Richard Rhodes: An interview with Dr. Stanislaw Ulam in Santa Fe, New Mexico, July 6, 1983.
Rhodes: Well I have some questions for you.
Ulam: Yes, of course. How long are you staying?
Rhodes: I am going to be in the area for until Saturday morning. It would be pleasant to see more of you. I thought I would go out to Los Alamos today and stay up there.
Ulam: There is a hotel.
Tell us your name.
Roger Rohrbacher: I'm Roger Rohrbacher. That’s R-O-H-R-B-A-C-H-E-R.
How did you come to Hanford?
Rohrbacher: In 1942 and '43, I was working for DuPont in an acid plant in Illinois and my buddies were disappearing. They ended up in Richland, so I got the map out and Richland, Pasco weren't even recorded on the map. I contacted them and I said, “What are you guys doing?”
They said, “We don't know.”
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.
Alexandra Levy: All right. We are here on April 23, 2015 with Mr. Rex Edward Keller. So first, can you please say your name and spell it.
Rex Keller: Oh, Rex Edward Keller, R-E-X E-D-W-A-R-D, Keller, K-E-L-L-E-R.
Levy: Can you tell me where and when you were born?
Keller: I was born in Saxton, Missouri, October 10, 1923.
Levy: And you grew up in Missouri?
Keller: Yes, yes, in Dexter, Missouri.
Wendy Steinle: Good morning, Ralph. I’m Wendy Steinle, as you know, and I am really pleased to be your friend and to have the opportunity to interview you this morning. Just for the record, will you start by stating and spelling your name, and then tell us the date?
Ralph Gates: Well, thanks, Wendy. My name is Ralph Gates, but I am—it’s Ralph Pillsbury Gates and I am a junior. It’s R-a-l-p-h, Pillsbury is P-i-l-l-s-b-u-r-y, and Gates is G-a-t-e-s.
Steinle: What is today’s date?
Ralph Gates is a chemical and electrical engineer who worked on the Manhattan Project as a part of the Special Engineer Detachment. His primary job was casting shape charges for the plutonium bombs.
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.
Murray Peshkin: Well, how did I get involved in the Manhattan Project? I was an undergraduate student at Cornell University. A group of about ten, who were studying physics. It was clear that we could not be kept out of the Army very long. They were looking for programs in which we could serve usefully. I really believed that there was something else behind it.
Murray Peshkin is a Manhattan Project veteran and a physicist. He was recruited by the Army to assist the Manhattan Project at Los Alamos when he was an undergraduate student studying physics at Cornell.
