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.

Harold Hasenfus' Interview

I was a member of two Special Engineer Detachments: I worked at the University of Chicago at the Metallurgical Laboratory and I also worked in Oak Ridge Plant, conceived and designed by Philip Abelson, who is probably here today. I lived in the barracks area when I was at Oak Ridge and I lived in an apartment with three other soldiers when I was in Chicago.

Chicago Met Lab

One of the most important branches of the Manhattan Project was the Metallurgical Laboratory (Met Lab) in Chicago. Using the name "Metallurgical Laboratory" as cover at the University of Chicago, scientists from the east and west coasts were brought together to this central location to develop chain-reacting "piles" for plutonium production, to devise methods for extracting plutonium from the irradiated uranium, and to design a weapon. In all, four methods of plutonium separation were considered, with the bismuth phosphate process displaying the most promise.
