In July 1945 William E. Tewes was transferred from New York, where he was working on gaseous diffusion, to Oak Ridge. He worked on the leak testing operation at K-25. He discusses the many scientific and engineering innovations of the K-25 Plant, raising a family in Oak Ridge, and the friends he made among his fellow Manhattan Project workers.
Herman Snyder worked on the Manhattan Project at Oak Ridge as a soldier in the Special Engineer Detachment. He worked at the K-25 Plant for many years, and later at the Y-12 Plant. He discusses the many innovations that caused K-25 to run so smoothly and to be built so quickly. Snyder also reminisces about the sense of community at Oak Ridge, and recalls having to scrounge a pass to get his new bride through the gates into Oak Ridge.
Winston Dabney applied to be assigned to the Manhattan Project and was transferred from Camp Claiborne, Louisiana to Los Alamos in early 1944. Shortly after he arrived, Dabney was promoted to Master Sergeant, where he was responsible for sending military records to Oak Ridge, organizing payroll, and ordering military supplies. In his interview, Dabney discusses what it was like to live and work at Los Alamos. He describes working conditions, recreational activities, and housing for military members and briefly touches upon religion and the quality of food. Dabney also discusses how he met his wife, Jean, and shares several funny stories involving some of the scientists who worked at Los Alamos.
Irénée Du Pont, Jr. was a member of the DuPont Company’s Executive Committee and is the son of Irénée Du Pont, president of the DuPont Company from 1919-1925. He was also the brother-in-law of Crawford Greenewalt, who coordinated the DuPont Company’s involvement with the Manhattan Project. In this interview, Irénée discusses the history of the DuPont Company, from its early work making gunpowder to the invention of nylon. He describes how the company became one of the key civilian contractors for the Manhattan Project.
Colonel James C. Marshall set up the Manhattan Engineer District (MED), established by general order on August 13, 1942. Marshall presided over the initial stages of the Project until General Leslie R. Groves assumed control on September 17, 1942. In this interview, Marshall discusses the military's involvement in the Manhattan Project and the challenges of securing funds, choosing project sites, and collaborating with scientists and officials. Marshall also discusses navigating government bureaucracy, going back and forth between different offices, seeking approval for various actions, and dealing with superiors with whom he often disagreed.
Lawrence Myers was a chemist who worked at the Oak Ridge during the Manhattan Project. In his interview, he discusses attending the University of Chicago, where he was invited to begin working on the Manhattan Project conducting experiments on uranium. He later moved to Oak Ridge along with a group of Chicago scientists. His wife joined him thanks to some chemistry coursework she had completed while in Chicago. Following the Project, Myers worked at Argonne National Laboratory before taking a position at the new medical school at the University of California, Los Angeles.
Denise Kiernan has worked as a journalist and producer. She is best known for "The Girls of Atomic City," which came out in March 2013 and immediately shot to the top of the New York Times bestsellers list. "The Girls of Atomic City" tells the story of the women who worked at Oak Ridge on the Manhattan Project. She has appeared on the Daily Show and NPR to talk about her book and the women who worked on the Manhattan Project.
Crawford Greenewalt was an American chemical engineer for the Dupont Company who acted as the liaison between the physicists at the Chicago Met Lab and the company's engineers in Wilmington, Delaware during the Manhattan Project. The challenge was to translate the scientists’ theoretical ideas into workable blueprints for the production of plutonium on a massive scale at the B Reactor being built in Hanford, WA. In this interview, Greenewalt discusses his role as a member of DuPont's review committee, which evaluated the different methods of fissile material production. Greenewalt, who was present at the University of Chicago when the first artificial self-sustaining nuclear reaction was set off, recalls the relatively calm atmosphere in the laboratory that day.
In this interview, General Groves discusses his relationship with some of the famous scientists who worked on the Manhattan Project, including J. Robert Oppenheimer, Harold Urey, Vannevar Bush, James B. Conant, and Ernest O. Lawrence. Groves also discusses the Chevalier incident and how Oppenheimer’s affiliation with the Communist party raised suspicions among fellow scientists of his motivations.
Walter Samuel Carpenter, Jr. was a corporate executive at DuPont who oversaw the company's involvement in the Manhattan Project. In 1919, at the age of thirty-one, Carpenter was elected to DuPont's board of directors, the first member who was not from the du Pont family. Carpenter discusses how DuPont came to be involved in the Manhattan Project, and how Groves' initial request seemed to be an almost impossible task. He also discusses the expansion of the American chemical business and the corporate structure of DuPont. Additionally, he touches upon his early life and how he initially got involved with the company after quitting school in the fall of his senior year at Cornell University to manage DuPont's Chilean nitrate interests.
