Charles Critchfield was a mathematical physicist assigned to work on the development of gun-type fission weapons, and eventually implosion-type weapons, at Los Alamos. He returned to Los Alamos in 1952 to work on the development of the hydrogen bomb.
Ted Taylor: I think Carson Mark is the most valuable resource to talk to about what happened in those days at Los Alamos. At Livermore, [Edward] Teller, certainly.
Richard Rhodes: Teller won't talk to me, I'm afraid. He’s decided I’m the enemy.
Reed Srere: Hi, I am Reed Srere – R-e-e-d S-r-e-r-e. I am recording this oral history for the Atomic Heritage Foundation on June 3  in Washington, DC. Please state your name.
David Fox: I am David Fox. I live in Providence, Rhode Island. My father was a physicist on the Manhattan Project in Manhattan. That is why I am here.
Srere: Please tell us your place and date of birth.
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?
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.
Kai Bird: This is Kai Bird off camera, interviewing Charles Oppenheimer and Dorothy Vanderford. Just for the record, I will ask you to state your names and your date of birth and where you were born.
Dorothy Vanderford: My name is Dorothy Vanderford. I was born as Dorothy Oppenheimer August 18th, 1973. I was born in Santa Fe, New Mexico.
William Downey: The depersonalization of the world, and what the Soviet Union does to their own people in mental hospitals in the process of destroying them, so all people would be destroyed everywhere. So, it is not the peace I want. It is not peace that I want. It is peace with justice. It is peace with freedom. It is peace that makes it possible for a man to dream his dream and stretch and strain and sweat to attain it. Without that, peace is a fraud and a delusion and a pretty word for tyranny. Do you follow me?
William Downey: Now, as I remarked, one of the security officers told me a little time before, there was going to be a really fantastic new thing, only one of the greatest things that ever happened in the history of the world. This kind of hyperbole I never took too seriously anyway.
Announcer: Here is your host and moderator, Milton Rosenberg.
Milton Rosenberg: Our guests tonight all know a great deal about the bombing of Hiroshima and Nagasaki, but from different vantage points, two of them from the vantage point of being up in the air and helping to drop the bombs. They are Fred Olivi, who was the co-pilot of Bockscar. That was the plane that actually delivered the bomb to Nagasaki.
Ross Simpson: All right, here’s the promo for Part One of the Nuclear War Series. I’m Ross Simpson on a bus, heading into Cheyenne Mountain, outside of Colorado Springs, Colorado. This is the home of NORAD, the North American Aerospace Defense Command. This is also where my five part series on the nightmare of nuclear war begins this morning.
