Crawford Greenewalt: Crawford Greenewalt. I’m named after my father, Crawford Hallock Greenewalt. The last name, Greenewalt, is spelled G-R-E-E-N-E-W-A-L-T. But in early years in the country, the Greenewalt’s spelled their name various ways. The present spelling may go back several generations.
Security & Secrecy
Gerhart Friedlander: My name is Gerhart Friedlander.
Interviewer: What was your role in the Manhattan Project?
Friedlander: I got into the Manhattan Project very early; in fact, before there was an official Manhattan Project. I was a graduate student at Berkeley at the University of California. My thesis advisor was Glenn Seaborg, who later on got a Nobel Prize and became chairman of the Atomic Energy Commission, but at that time he was just a new instructor and I was his first graduate student.
Ernest Tremmel: I'm Ernie Tremmel.
I graduated from the University of Wisconsin in civil engineering, and I went to work for the Corps of Engineers in St. Louis. One of my bosses was a Captain Powell who, after I was in St. Louis two years, got transferred to a secret project he was going to work on called the Manhattan Project Corps of Engineers.
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.
Stephane Groueff: Mr. Hobbs, part three.
J.C. Hobbs: The discussion in connection with piping and all of these fancy bends. Badger Company in Boston, I think, had the contract for the copper expansion joints.
Groueff: Between pipes?
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.
Harry Allen: Mr. Wilson and company set us up a purchase request for a barber chair, because they couldn’t get off work in time to get their hair done.
Robert Van Gemert: There was only one man cutting hair, I think, up there.
Allen: The barber service was extremely limited, and we just happen to know where there was an old barber chair down in the old engineers’ warehouse. So we sent the truck driver down, and we delivered one barber chair down to the cyclotron building.
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?
General Kenneth Nichols: —found we did not have the authority to satisfy DuPont.
Stephane Groueff: But why did DuPont challenge your authority?
Nichols: Because they had trouble, in World War I, being called munitions makers and investigated after World War I, so they are more conservative than most companies. And they wanted to have in their files copies of our authorities. And what we had, which I have shown you, and that is satisfactory to them.
Groueff: I see.
Tom Ryan: In the early morning of August 6, 1945, three B-29 bombers departed from Tinian Island in the Pacific Ocean. Six hours later, they changed the course of history. A single atomic bomb dropped from the Enola Gay exploded over Hiroshima, Japan. In an instant, over four square miles of the city and an estimated 90,000 of its inhabitants ceased to exist.
