Jim Eckles worked for decades for the White Sands Missile Range Public Affairs Office, managing open houses and tours of the Trinity site, where the world’s first nuclear test took place. In this interview, Eckles describes the history of Trinity site. He discusses the ranchers who lived on it before the Manhattan Project took over, the buildings used by the scientists, and what it was like to live on the site before and during the war. He provides an overview of the Trinity Test and the “Gadget,” 100 ton TNT test, and the making of “Jumbo.” Eckles also discusses some of the key workers at Trinity site, including scientists, technicians, photographers, and MPs. He also explains some of the controversy around the site, including radiation levels, concerns over fallout from the test, and the atomic bombings of Japan.
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.
