F. Weisskopf and J. B. French….

CALTECH
Three local histories are Judith Goodstein’s Millikan’s School, Ann Scheid’s Pasadena: Crown of the Valley, and Kevin Starr’s Inventing the Dream; they were useful background, as was Robert Kargon’s essay ‘Temple to Science.” I’ve also relied on the recollections of many present and former Caltech professors, students, and administrators. Some information on Feynman’s time in Brazil comes from the recollections of José Leite Lopes (1988 and personal communication), Cecile Dewitt-Morette, and others; from Feynman’s 1951 correspondence with Fermi; from Brownell 1952; from Feynman’s talk “The Problem of Teaching Physics in Latin America” (1963a), and from publications of the Centra Brasileiro de Pesquisas Fisicas. Documentation of the government’s secret scrutiny of Feynman and of his consultation with the State Department on the advisability of travel to the Soviet Union came through my Freedom of Information Act requests to the FBI, CIA, Department of the Army, and Department of Energy in 1988 and 1989. Some of the State Department correspondence is also in CIT. On superfluidity, Robert Schrieffer, Hans Bethe, Michael Fisher, and Russell Donnelly were especially helpful. Donnelly sent written reminiscences by several colleagues. Andronikashvili 1990 is a remarkable memoir from the Russian perspective. For the particle physics of the 1950s and 1960s: the Rochester conference proceedings; John Polkinghorne’s witty memoir (1989) and Jeremy Bernstein’s “informal history” (1989); Robert Marshak’s account (1970); Brown, Dresden, and Hoddeson’s symposium proceedings Pions to Quarks: Particle Physics in the 1950s; and interviews with the various scientists cited. Again, some material on personal relationships is based on letters and interviews that I cannot cite specifically for reasons of privacy. Feynman’s thinking on gravitation can be seen in a fifteen-page letter to Victor Weisskopf written in January and February 1961 (WHE) and in his Faraday lecture (1961b), as well as his one published paper (1965b) and various lecture notes in CIT. The development of quarks and partons has been well chronicled from different points of view by Andrew Pickering (1984) and Michael Riordan (1987); Feynman kept his notes from this period in unusually good order (CIT); Riordan and Burton Richter provided useful on-site guidance at the Stanford Linear Accelerator Center; James Bjorken, George Zweig, Sidney Drell, Yung-Su Tsai, and, of course, Murray Gell-Mann were among those with especially helpful reminiscences. For the record of Feynman’s illnesses I relied on notes and correspondence in his files and interviews with Drs. C. M. Haskell, William C. Bradley, and In Chang Kim. For the investigation into the Challenger accident: the hearing transcripts and documentation as published in the commission report; Feynman’s personal notes and commission memorandums (CIT and PERS); Ralph Leighton’s unedited transcript of Feynman’s oral account (later published in WDY); interviews with commissioners, NASA officials and engineers, and others (only William P. Rogers refused to make himself available, despite my repeated requests for an interview). Carl Feynman shared the manuscript of the paper Feynman was working on until he entered the hospital for the last time.

ht: maybe I won’t take the prize. All right? And I worried about it, because in a certain sense I felt that was unfair. The guy is offering the money—you know, he’s trying to do something nice— and it isn’t that he just did it because of this, because he’s done it before. There were previous Einstein Awards, as far as I know, or something…. I was kind of confused. “F-W, 673–74.
