D. M. Ellett is a mechanical engineer who joined the Manhattan Project after the end of World War II. He was a member of Z Division, which was assigned to Sandia Base in Albuquerque, New Mexico in 1945. In the interview, Ellett recalls his arrival in Albuquerque and shares stories from his long career at Sandia (today, Sandia National Laboratories). He describes his years as a docent at the National Museum of Nuclear Science and History, and recalls witnessing a nuclear test in Nevada.
Norris Bradbury was an American physicist and director of the Los Alamos National Laboratory from 1945-1970. During the Manhattan Project, Bradbury directed the implosion field test program and helped prepare the “Gadget” for the Trinity test. In this interview, Bradbury explains why he was selected to work at Los Alamos, and discusses his work on the plutonium implosion bomb. He recalls his interactions with Manhattan Project leaders J. Robert Oppenheimer, George Kistiakowsky, and Admiral Deak Parsons. Bradbury watched over the “Gadget” at the top of the Trinity test tower to ensure that no one “monkeyed” around with it. He remembers his surprise when Oppenheimer picked him to take over as director of the laboratory, and the challenges he had to overcome to keep the lab up and running.
