Carl D. Anderson was a physicist who won a Nobel Prize for the discovery of the positron. He studied and taught at the California Institute of Technology (Caltech), where he took a class with a young professor named J. Robert Oppenheimer. In this interview, he discusses his impressions of Oppenheimer, including Oppenheimer’s early struggles as a teacher. Anderson describes the research that was going on at Caltech during the 1930s, including the groundwork that went into his Nobel-winning discovery. He also details why he turned down a role on the Manhattan Project, and the work he did on rockets during World War II instead.
Jean Dow Bacher was born in 1907, and grew up in Ann Arbor, Michigan. She married fellow Ann Arbor native and leading Manhattan Project scientist Robert Bacher in 1930. Jean was a “computer” at Los Alamos during the Project. In this interview, she describes the friendship her and her husband shared with the Oppenheimers, and their interactions with other scientists and their families at Los Alamos. Bacher recalls how observers who visited Hiroshima and Nagasaki were “appalled and stunned” at the destruction there, and explains how J. Robert Oppenheimer and others at Los Alamos tried to come to terms with their work on the bomb. She recounts Oppenheimer’s anxiety about being under surveillance in the lead up to his security hearing. She also recalls Edward Teller’s habit of playing the piano late at night, and shares her impressions of Kitty Oppenheimer.
William A. “Willie” Fowler was a Nobel Prize-winning physicist at Caltech, who knew J. Robert Oppenheimer from before the war. In this interview, he talks about how Oppenheimer and his “school” of students and post-docs would travel each year from the University of California, Berkeley to Caltech, where Oppenheimer had an appointment on the faculty. He describes how Oppenheimer’s theoretical knowledge and perspective supplemented the experimental research being conducted at Caltech, including Fowler’s own. He also talks about the lives and careers of other physicists who interacted with Oppenheimer in Pasadena, including Charles Lauritsen, Richard Tolman, and Robert Millikan. The interview concludes with a discussion of Fowler’s friendship with Frank and Jackie Oppenheimer.
