Harold E. Hoover's Interview

Harold Hoover: My name is Harold E. Hoover, that’s H-O-O-V-E-R, commonly known as Hal, H-A-L.

Cindy Kelly: Why don’t you start by telling me how you got into the SED [Special Engineer Detachment]? How you happened to get into the SED, and then what you found when you got to Oak Ridge?

Leon Love and George Banic's Interview

[Audio distortion occurs throughout the interview.]

Stephane Groueff: Recording interview with Mr. Leon Love at Oak Ridge July 15, 1963. Mr. Love works with Y-12.

Would you mind repeating sort of some of the characteristics of Y-12, some of the figures? For instance, how many buildings? How many magnets? How many Alpha [calutrons] and Beta [calutrons]? How many units in each?

Leon Love: There were five buildings containing the output separators, and there were nine tracks total in these five buildings.

Robert J.S. Brown's Interview

Robert JS Brown: I'm Robert JS Brown.

Robert S. Norris: You are recording this oral history for the Atomic Heritage Foundation on June third, two thousand fifteen in Washington, DC.

Brown: Yes, right.

Robert S. Norris: How did you become involved in the Manhattan Project? Can you tell us about that?

Bob Carter's Interview (2015)

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.

The Hiroshima Mission

Narrator: Apparently aloof from the rest of World War II, the solitary 509th, still unaware of its own purpose, carries on its puzzling training schedule. Their orders: practice runs to nearby islands. Then their own private missions to Japan, always above thirty thousand feet, always alone or in threes, always to drop just one bomb. Each time they must return to Tinian to face the ridicule of their fellow flyers. A poem is written in their dubious honor.

Jacob Beser's Lecture

Jacob Beser:  The story which we could tell. And one point that Dr. Wittman, though, which I wish you would please keep in mind—and this is true not only in this situation, but any historical event  should be evaluated in the context in which it took place, the context and the times in which it took place. Hopefully we proceed from there and progress. Forty years later, we all had 20/20 hindsight and we also have had access to archives and information that we did not have forty years ago.
