Murray Peshkin's Interview

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.

Tom Gary's Interview - Part 1

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.
