Fred Hunt's Interview

Hunt: I started working for DuPont in 1937 at Old Hickory [in Tennessee] in the power department. I was very anxious to do the best I could, so I made a special effort to learn everything.

Where were you when you were told to return to Wilmington?

Hunt: At that point I was a power superintendent at Childersburg Ordnance.

That was in Alabama?

Hunt: In Alabama.

When did you find out about Hanford?

Joseph Katz's Interview

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.

Lew Kowarski's Interview - Part 2

Stephane Groueff: One thing I don’t understand, and it’s a very ignorant question, but what was actually the difference between [Enrico] Fermi’s experiment in ’34 and [Otto] Hahn’s? Because, why do we say that Hahn was the first one, while Fermi also bombarded uranium?

Lew Kowarski: I don’t it’s true to say that Hahn was the first one.

Groueff: It’s not true.

Kowarski: I think it’s one of those simplifications—there are people who find them all right. I don’t.

Ray Gallagher and Fred Olivi's Interview - Part 1

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.

Nuclear War Radio Series

Ross Simpson: All right, here’s the promo for Part One of the Nuclear War Series. I’m Ross Simpson on a bus, heading into Cheyenne Mountain, outside of Colorado Springs, Colorado. This is the home of NORAD, the North American Aerospace Defense Command. This is also where my five part series on the nightmare of nuclear war begins this morning.
