The Manhattan Project


Louis Hempelmann's Interview - Part 2

Louis Hempelmann: He [J. Robert Oppenheimer] just told me what the situation was. He did not ask me, which is the same thing when he got sick because I was in the radiology department here and I knew something about it. He would call me up, tell me what he had done, and then say “What do you think of it?” By that time, the only thing I could say was, “That was fine.”

Jack Widowsky's Interview

Alexandra Levy: We are here on June 13th in New Jersey with Jack Widowsky. This is Alex Levy with the Atomic Heritage Foundation. My first question for you, Jack, is to please say your name and to spell it.

Jack Widowsky: My name is Jack Widowsky. J-A-C-K, which is easy, but the last name is W-I-D-O-W-S-K-Y.

Levy: Can you please tell me where you were born and when?

Widowsky: I was born in Newark, New Jersey, on September 10, 1922.

Kathleen Maxwell's Interview

Nate Weisenberg: My name is Nate Weisenberg. I am doing this interview for the Atomic Heritage Foundation with Kathleen Maxwell here in Wellesley, Massachusetts. It is Monday, April 25, 2016.

How did you get involved with the Manhattan Project?

Kathleen Maxwell: I had just finished my Master’s degree at Smith [College], and I was contemplating staying at Smith because the main men in our department there had gone to work for the Manhattan Project someplace else.

University of Rochester

Small experiments studying the effects of radioactive isotopes, including plutonium, uranium, and polonium, on humans were conducted in the Manhattan Annex of the Strong Memorial Hospital located at the University of Rochester. The purpose of these studies was to examine the safety of small amounts of radiation on those working at other Manhattan Project sites.

Mack Newsom's Interview

Cindy Kelly: I’m Cindy Kelly. It is Sunday, May 15, 2016, and I’m in Houston, Texas. I’m here to interview Mack Newsom. My first question for you is to say your formal name and spell it.

Mack Newsom: My full name is Mack Newsom, M-A-C-K. Well, originally it was Victor McKee, but they call me Mack. V-I-C-T-O-R and M-C-K-E-E, McKee.

Louis Hempelmann Interview - Part 1

Martin Sherwin: Martin Sherwin, I am about to interview Dr. Hempelmann at Strong Memorial Hospital.

You know, simply from all of the Los Alamos records, but who told me you were at Strong? That was, I think, Dorothy McKibbin.

Louis Hempelmann:  Oh yeah.

Sherwin: No, she confirmed it. She said you were coming out to Santa Fe.

Hempelmann: Yeah.

Siegfried Hecker's Interview - Part 3

Siegfried Hecker: Okay, I was just—a little bit more on the testing business. Again, I will not give you much because eventually, I am sure you will do all the research on this. There are some interesting dynamics in the testing business all the way around, because it is such an emotional issue. So hard drawn on both sides, almost a little bit like abortion. You just cannot seem to bring people together. They are either in one camp or in the other.

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.
