Nancy Greenewalt Frederick: My father, Crawford Greenewalt, was the only child of Dr. Frank Lindsay Greenewalt and Mary Hallock Greenewalt. Dr. Greenewalt was a physician at Gerard College in Philadelphia, and my father grew up there most of his young life. He went to a German school, what we would call a preschool, run by German monks when he was a child. He says he spoke German before he spoke English. But when he was grown up he could do some German, but he couldn’t speak it.

Hans Bethe: The other was M - A - D, MAD [Mutually Assured Destruction], which essentially says that nuclear weapons make sense only as a safeguard against nuclear weapons. As [Wolfgang] Panofsky has said recently, and there is actually an article by him, "It is not a doctrine. It is a fact of life. Nothing else is possible, whatever you might wish.” So I think you should not present it as something really unavoidable, without any movements in the opposite direction.  

 Martin Sherwin: This morning I am making arrangements to interview Norris Bradbury in Los Alamos, New Mexico. January 10, 1985.

How would you characterize the major problems that [J. Robert] Oppenheimer had when he first got the job as the administrator for Los Alamos? Or at least, when you came on?
