Raemer Schreiber: I think the only point that is of any interest in this regard to pick up is perhaps the fact that the group of us who came here to work on the so-called water boil reactor had been working together at Purdue University on the very first measurements of the so-called deuterium tritium cross sections, which has to do with the fusion reaction. This eventually was used in bombs, but not for many years, and it is, of course, the basis for present attempts to create energy by controlled thermonuclear reactions or fusion reactions.
Richard Foster: This is Dick Foster.
S. L. Sanger: Hi, this is Steve Sanger in Seattle. I wrote you a letter a few days ago after my conversation with Hanford. Did you get that?
Foster: Yeah I just got home yesterday evening.
John Healy: Hello.
S. L. Sanger: Hello this is Mr. Sanger from Seattle, is this a good time to talk about Hanford, or no.
Healy: Another one you may want to talk to is Carl Garmertsfelder in Knoxville.
Sanger: In Knoxville, now what was his position? Oregonian said he was a radiation control manager.
Healy: It has been so long. I do not really remember. I worked for Carl for a while, and he reported to Herb Parker.
Richard Baker: The first plutonium that, other than the cyclotron that produced plutonium, was made at what was called the Clinton Piles at old X10 down in Oak Ridge. The Chicago Met Lab worked on the micro scale reduction of the metal. This produced rather small quantities but never enough quantities to study its properties in any accurate manner.
Joseph Katz: Now it was recognized that plutonium would have a chemistry that would be quite similar to that of uranium. And developing procedures for the separation of plutonium from irradiated uranium. The assumption that was most commonly made was that the chemistry of plutonium would be similar, if not identical to that of uranium and this, of course was an entirely reasonable assumption to make.
Announcer: Here is your host and moderator, Milton Rosenberg.
Milton Rosenberg: Our guests tonight all know a great deal about the bombing of Hiroshima and Nagasaki, but from different vantage points, two of them from the vantage point of being up in the air and helping to drop the bombs. They are Fred Olivi, who was the co-pilot of Bockscar. That was the plane that actually delivered the bomb to Nagasaki.
Michele Gerber: My name is Michele Gerber, M-I-C-H-E-L-E G-E-R-B-E-R.
Why should people today care about the Manhattan Project?
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.
