Eulalia “Eula” Quintana Newton worked at Los Alamos for a total of 53 years, beginning in 1944. She received a Distinguished Performance Award for her exceptional service to the Los Alamos laboratory. In this interview, she discusses the many jobs she held at Los Alamos. After working in the housing and secretarial departments, she eventually rose to the position of group leader in the mail and records department. Quintana Newton recalls being the first Hispanic woman without a college degree to become a group leader at the laboratory. She also describes the impact of Los Alamos and the Manhattan Project on the Española Valley community.
W. Stanley Hall was eighteen years old when he was recruited to work as a machinist on the cyclotron, first at Princeton University and later at the Los Alamos Laboratory. He worked at Los Alamos as a civilian, then later was drafted and worked as part of the Special Engineer Detachment (SED). In this interview, he describes both his work and recreational experiences during the Manhattan Project. He witnessed the Trinity Test from a location ten miles away. Hall describes hearing “The Star Spangled Banner” play over the radio at the moment of the Trinity Test and the color and the noise of the explosion. Hall also talks about taking advantage of the hiking, fishing, and horseback riding opportunities around him, including some trouble he encountered walking Kitty Oppenheimer’s horse. He provides an overview of his forty-year-long career at Los Alamos National Laboratory, where he working for the computing group.
Jay Shelton is an American physicist and science and math teacher. In this interview, he recalls his experiences from nearly three decades as a high school teacher in Northern New Mexico. He provides an overview of how radiation works and how alpha, beta, and gamma rays differ. Shelton explains the health risks associated with radiation and stresses the importance of quantitative analyses of risks from certain radiation sources. He argues that the general public often overplays many of these risks. He also goes over changes in public perception towards radiation. For example, he points out that radiation was believed to have health benefits prior to the 1930s. Throughout the interview, Shelton describes how a variety of scientific instruments work, including Geiger counters and oscilloscopes, and expounds on the importance of a hands-on approach in science education. He also discusses his personal collection of scientific artifacts, including Revigators and other nuclear-related objects.
Clay Kemper Perkins is a physicist, philanthropist, and collector of Manhattan Project artifacts and replicas. In this interview, he discusses his vast collection of weapons and how he became interested in nuclear weapons and Manhattan Project history. He describes some of the stand-out pieces in his collection, including the safety plug used in the Little Boy atomic bomb on the Hiroshima mission and a full-scale replica of Little Boy. He also explains the role of high-speed cameras in the Trinity Test and the “pin domes” that Manhattan Project scientists experimented with for the implosion bomb. Perkins also discusses his philanthropic contributions to the Los Alamos Historical Society, including his purchase and gift of the Hans Bethe House.
Bruce Cameron Reed is a physicist and a professor at Alma College. In this interview, he discusses a course he teaches at Alma about nuclear weapons and the Manhattan Project. He explains how he became interested in the physics and history of the Manhattan Project. He provides an overview of some of the challenges the Manhattan Project scientists faced and why uranium, plutonium, and polonium are so difficult to work with. Reed describes some of the innovations of the project, including the implosion design and lenses, the tamper, and the polonium initiator. He concludes by sharing his thoughts on some of the ethical issues related to nuclear weapons.
Nick Salazar is a longtime Los Alamos National Laboratory employee and New Mexico State Representative. He has remained close to Los Alamos his entire career, from spending his high school summers as a mess hall attendant during the Manhattan Project to becoming a member of the laboratory’s Board of Governors. In this interview, he discusses his numerous experiences with the laboratory, including his 42-year career as a research scientist and his goal of improving relations between the laboratory and northern New Mexico’s communities. He also recalls traveling to the Savannah River Site as part of Clyde Cowan and Frederick Reines’s famous experiment that discovered the neutrino.
Lydia Martinez, from the neighboring community of El Rancho, worked at Los Alamos in various jobs during and after the Manhattan Project. She first worked as a baby-sitter and housekeeper for families such as the Fermis, Tellers, and Critchfields. She was also a junior technician in the X-7 group. After the war, she remained at Los Alamos National Laboratory, working in various units and finally retiring as a property administrative specialist. In this interview, she remembers her duties at Los Alamos and what it was like to be one of the younger women who worked there. She describes how she continued to keep ties with various families over the years, and recalls how she received the Laboratory’s Distinguished Performance Award.
Isabel Torres worked at Los Alamos during and after the Manhattan Project. She commuted from the neighboring community of Santa Cruz, first by truck, then by bus. She worked in the administration office and as a classified mail messenger. In this interview, Torres remembers how her job granted her access to different areas of the laboratory. She mentions interactions with soldiers and prominent scientists, including Edward Teller. She also describes working at S-Site as a technician, and recalls the poor condition of the roads.
Milton Levenson is an American chemical engineer and former president of the American Nuclear Society who has worked in the nuclear energy field for more than 60 years. During the Manhattan Project, he worked at Decatur, IL, and Oak Ridge, TN, where he was a supervisor at the X-10 plant. In this interview, he describes how he joined the Manhattan Project and his experiences at Oak Ridge, including his memories of segregation there. Levenson then talks about his post-war career as an expert on nuclear safety, including his role in responding to the SL-1, Three Mile Island, and Chernobyl accidents. He also recalls having to tell Enrico Fermi that he could not perform an experiment for safety reasons.
