Oral Histories

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.

Jennet Conant is an author who has written extensively on the Manhattan Project and some of its most prominent figures. Some of her books include “The Irregulars: Roald Dahl and the British Spy Ring in Wartime Washington” and “Man of the Hour: James B. Conant, Warrior Scientist.” In this interview, Conant describes some of the stories she writes about in her book “109 East Palace: Robert Oppenheimer and the Secret City of Los Alamos.” Specifically, she focuses on the life of Dorothy McKibbin, the “Gatekeeper to Los Alamos,” and her contributions to the Los Alamos laboratory during the war. She also discusses the Trinity Site, Klaus Fuchs’s espionage, and the stresses the Manhattan Project put on relationships between scientists and their families.

Felix DePaula was an Army private stationed at the Trinity Site and Los Alamos during the Manhattan Project. After the war, DePaula stayed at Los Alamos, and worked for the Zia Company there. In this interview, DePaula talks about life at Trinity Site, especially the isolation and the entertainment he and his fellow soldiers would come up with to pass the time. He describes the rodeos the military police would help set up. DePaula also witnessed the Trinity test, and talks about the feeling among the troops after seeing the detonation. He also recalls the high security at the gates to Los Alamos.

Louis Hempelmann was J. Robert Oppenheimer’s physician and close friend. In this interview, he discusses the hierarchy at Los Alamos, what it was like to work with Kitty Oppenheimer, and Kitty and Robert’s relationship. He recalls his interactions with Oppie, Enrico and Laura Fermi, and Edward Teller, and the parties that Oppenheimer and others used to throw at Los Alamos. Hempelmann remembers driving to Trinity Site with George Kistiakowsky and the high explosives—on Friday the 13th.

In his interview, Rex Edward Keller recalls his journey from Dexter, Missouri to Los Alamos, where he joined several of his childhood friends as well as his brother, Keaton Keller. In the summer of 1943, he arrived in New Mexico as a civilian worker, but was later drafted as a member of the Special Engineer Detachment. Keller worked in the Chemistry Division and later in Seth Neddermeyer’s implosion group, testing the explosives. He remembers the social life of the community in Los Alamos and the relationships between the civilian scientists and the military officials involved in the project.
