Walter Goodman

Walter Goodman was recruited into the Special Engineer Detachment at Los Alamos in 1943. Goodman worked as an electrical engineer on the implosion bomb and helped design equipment to measure the efficiency of an atomic blast. In July 1945, Goodman deployed to Tinian Island to help prepare the Fat Man bomb to be dropped on Japan. On August 9, 1945, he witnessed the bombing of Nagasaki from the instrumentation aircraft The Great Artiste and took motion pictures of the mushroom cloud above the city.

David P. Rudolph

David R. Rudolph was an administrator in charge of inventory at the Chicago Metallurgical Laboratory. In his interview, he discusses how he was one of the few individuals to be present at both the startup of Chicago Pile-1 and the Trinity test. Rudolph recalls the process of reactor construction, along with the disassembly of CP-1 for the construction of CP-2. He explains the importance of inventory control when it came to the uranium and graphite blocks used in CP-1, and how he helped discover that a section had not be stacked with enough blocks.

Henry Frisch

Andrew Hanson is the son of Alfred Hanson and Henry Frisch is the son of David Frisch. Alfred and David were both physicists who worked on the Van de Graaff long tank, first at the University of Wisconsin and then at Los Alamos. Both physicists were using the long tank to measure neutron cross sections in plutonium. In this interview with Robert S. Norris, Frisch and Hanson discuss their father’s work at Los Alamos and relay a number of anecdotes their parents told them about life at Los Alamos.

Bob Carter's Interview

Kai Bird: Let us begin at the beginning and I think the viewers of this will want to know first about your own background. What year were you born?

Bob Carter: I was born in 1920 in Philadelphia, Pennsylvania.

Bird: On what day?

Carter: February 3, 1920.

Bird: 1920.

Carter: Yes.

Bird: Okay, 1920, what was sort of before modern physics, quantum physics was invented as such.
