Martin J. Sherwin's Interview

Cindy Kelly: I’m Cindy Kelly, Atomic Heritage Foundation, Washington, D.C. It is Monday, April 24, 2017. I have with me distinguished historian and Pulitzer Prize-winner Martin J. Sherwin. My first question to him is to say his name and spell it for us.

Martin Sherwin: Martin J. Sherwin, M-A-R-T-I-N, middle initial J—actually, middle name Jay, J-A-Y, Sherwin, S-H-E-R-W-I-N.

Kelly:  Can you tell us when [J. Robert] Oppenheimer was born and where, and who his parents were?

Richard Money's Interview

Willie Atencio: The first thing we need to know is, where were you born?

Dick Money: In Chicago.

Atencio: Okay, you were born in Chicago. What part of Chicago?

Money: South Side.

Atencio: South Side. Tell us a little bit about your parents.

Money: My father was a civil engineer. He had a company that built grain elevators. He was educated at Armour Institute, which later became Illinois Tech in Chicago. A wonderful man, of course.

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.

Hanford 25th Anniversary Celebration

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.

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.
