Benjamin Bederson, a New York native, was selected to serve in the Special Engineering Detachment during the Manhattan Project. A physicist, he was first sent to Oak Ridge, and then to Los Alamos, where he worked for Donald Hornig on designing the ignition switches for the implosion bomb. At Los Alamos, he knew Ted Hall and David Greenglass, who were secretly sending atomic bomb secrets to the USSR. Bederson instructed the 509th Composite Group at Wendover and was sent to Tinian to help wire the switches for the bomb.

Martin Sherwin: I’m interviewing Robert Serber at his home in New York City. Date is January 9th, 1982.
Let me just begin at the beginning and ask you, how did you get to Berkeley? Why did you go there?
Serber: I got my degree at Wisconsin with [John] Van Vleck, and that was ’34. You didn’t have very many choices of what you can do. But I got a National Research Fellowship, which, if I recall, there were only five of them available that year. That was a year when the new membership of the American Physical Society was thirteen.
Alexandra Levy: We are here on June 13th in New Jersey with Jack Widowsky. This is Alex Levy with the Atomic Heritage Foundation. My first question for you, Jack, is to please say your name and to spell it.

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.
