Roger Hildebrand's Interview

Cindy Kelly: I’m Cindy Kelly, and it is November 16, 2016. I’m in Chicago, Illinois with Roger Hildebrand. My first question for him is tell me your name and spell it, please.

Roger Hildebrand: My name is Roger Hildebrand, R-o-g-e-r H-i-l-d-e-b-r-a-n-d.

Hanford 25th Anniversary Celebration

[Many thanks to Claude Lyneis for donating this footage to the Atomic Heritage Foundation.]

Narrator: About seventy-five miles northwest of Walla Walla, Washington, in an isolated expanse of open desert, civilization entered into a new age, an age from which it would never emerge the same. Here, in the home of the Wanapum Indians, the terrain is mostly scrubland, laced here and there by cheatgrass, greasewood, and Russian thistle.

Gerhart Friedlander's Interview

Gerhart Friedlander: My name is Gerhart Friedlander.

Interviewer: What was your role in the Manhattan Project?

Friedlander: I got into the Manhattan Project very early; in fact, before there was an official Manhattan Project. I was a graduate student at Berkeley at the University of California. My thesis advisor was Glenn Seaborg, who later on got a Nobel Prize and became chairman of the Atomic Energy Commission, but at that time he was just a new instructor and I was his first graduate student. 

Ernest Tremmel's Interview

Ernest Tremmel: I'm Ernie Tremmel. 

I graduated from the University of Wisconsin in civil engineering, and I went to work for the Corps of Engineers in St. Louis. One of my bosses was a Captain Powell who, after I was in St. Louis two years, got transferred to a secret project he was going to work on called the Manhattan Project Corps of Engineers.  

Clarence Larson's Interview

Stephane Groueff: Interview with Dr. Clarence Larson—L-A-R-S-O-N—head of the Union Carbide’s operations at Oak Ridge, a chemist. Dr. Larson was connected with the electromagnetic separation process during the war, and he was a personal friend of Dr. Lawrence [Ernest O. Lawrence]. He’s married to the daughter of Dr. Stafford Warren, who was also with the project. You came in 1942?

Dr. Clarence Larson: Yes.

Groueff: From where?

Jerome Karle's Interview

Jerome Karle: My name is Jerome Karle. And it is J-E-R-O-M-E K-A-R-L-E.

Cindy Kelly: Great. Dr. Karle, can you tell me about what you were doing in the early 1940s and how you happened to become part of the Manhattan Project?

Karle: Well, I had just finished my work in 1943, for my graduation on my degree.

Isabella Karle: Your PhD.

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.
