Clarence Larsen

Dr. Clarence Larsen, a chemist, began working under Ernest Lawrence in his lab at the University of California, Berkeley in 1942. While Lawrence and his team were engineering the cyclotron, Larsen was on hand to ensure chemical processing was sound. His primary concern was not the cyclotron itself, but its product and the ability of that product to produce an explosion.

Marge Shipley's Interview

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.

Tom Gary's Interview

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.

Dale Babcock's and Samuel McNeight's Interview (1965)

Stephane Groueff: Recording from Wilmington, Delaware. DuPont Company.

Samuel McNeight: I’ll say the major part of the reason why I ask Dale to come over with me was that Dale’s acquaintanceship and part in the Manhattan Project considerably pre-dates mine. Also, he was a part of the reactor group, which I was not. I had nothing to do with reactors.

Groueff: You had to do with the separations?

McNeight: The separations plants entirely.

Arthur Squires's Interview - Part 1

Arthur Squires: And I probably did not appreciate, during the war itself, the extent to which this was such a remarkable effort. Kellex – I am sure some of this you have already heard. Kellex was put together by M.W. Kellogg Company pretty much on a command basis. They just went to the top people all over the industry and got the top instrument man, the top man in the power field, and top people in compressors and all the various phases of the project.
