202 AN ARMY CAR MET HIM: Feynman to Lucille Feynman, 9 August 1945, PERS.

204 NO MONOPOLY: Notes, n.d., PERS.
204 MOST WAS KNOWN: Ibid.
204 IT WOULD SEEM TO ME THAT UNDER THESE CIRCUMSTANCES: Oppenheimer to Birge, 26 May 1944, in Smith and Weiner 1980, 276.
204 BIRGE FINALLY CAME THROUGH: Oppenheimer informed Birge of Feynman’s choice in a blisteringly formal tone: “I am glad that you are going to take steps to increase the strength of the department…. Several months ago Dr. Feynman accepted a permanent appointment with the Physics Department at Cornell University. I do not know details of salary and rank, but they are presumably satisfactory to him. I shall of course do my best to call to your attention any men who are available …”(5 October 1944, in Smith and Weiner 1980, 284). The California offer did prompt Cornell, at Bethe’s urging, to raise Feynman’s salary before he arrived. His “potential” salary was $3,000; when Berkeley offered $3,900, Cornell agreed to $4,000. Bethe had written: “I know that it is unusual to raise a man’s salary before he has even seen the University at which he is employed. The justification, I believe, is given by the unusual times and by the intimate knowledge that we here have acquired of Feynman’s qualities.” Bethe to R. C. Gibbs, 24 July 1945, and Gibbs to Feynman, 3 August 1945, CIT.
205 FEYNMAN BECAME THE FIRST OF THE GROUP LEADERS: Hawkins et al. 1983, 304.
205 IT WAS ON HIS LAST TRIP: WYD, 53.
CORNELL
Bethe provided access to his papers. Dyson shared copies of his remarkable letters home during these years (my portrait of him relies on these, on his various memoirs, on Brower 1978, and on Schweber, forthcoming). Schwinger collected the key scientific texts (1958) and gave his own rich perspective (1983). They and the other central figures in the postwar development of quantum electrodynamics all provided their oral recollections, as did Theodore Shultz, Michel Baranger, Evelyn Frank, Arthur Wightman, Abraham Pais, and others. Paul Hartman (1984) shared his entertaining history of the Cornell physics department and correspondence with Feynman about space flight. My discussion of scientific visualization is indebted to Arthur Miller 1984 and 1985, Bruce Gregory 1988, Schweber 1986a, Park 1988, essays by (and a conversation with) Gerald Holton, and Feynman’s own introspection. My accounts of Feynman’s relationships with women, in this chapter and the next, are based on correspondence in his personal papers and on my interviews with each of the women whose relationships are described in any detail; however, in the notes that follow, I usually omit individual citations of these letters and interviews for reasons of privacy.

212 SPEECH PATTERNS STRUCK HIM: “It was completely—like the nervousness of working during the war. And this university in the backwoods … was going at the typical university rate … he’s talking so slowly and batting the breeze about the weather.” F-W, 418.
212 OUTSIDE, THREE TENNIS COURTS: Hartman 1984, 204–5.
212 MORRISON HAD BEEN LURED: Philip Morrison, interview, Cambridge, Mass.
212 FEYNMAN DEPRESSED IS JUST A LITTLE MORE CHEERFUL: Quoted in Schweber 1986a, 468; Feynman said, “I got deeper and deeper into a kind of— I wouldn’t say depression, because I wasn’t depressed. I’m a lively and happy fellow….” F-W, 425.
212 HE SPENT TIME IN THE LIBRARY: SYJ, 155.
212 HIS DANCE PARTNERS LOOKED ASKANCE: F-W, 423; SYJ, 154.

223 FEYNMAN’S VERSION OF THE STORY: F-W, 620; SYJ, 137. The latter was dictated more than twenty years later but sometimes tracks the first version with uncanny, verbatim precision. The Selective Service files were destroyed, as the FBI discovered in assembling its dossier on Feynman. FOI.
226 FEYNMAN WAS INVITED: Princeton University 1946; F-W, 433–34; Wigner 1947; Feynman to Dirac, 23 July 1947, PERS.

226 FEYNMAN LOOKED OUT THE WINDOW: F-W, 437.
226 HE HAD A QUESTION: Ibid., 272–73 and 437; Feynman 1948a, 378. Feynman cared about this detail of historical priority. He later emphasized it in his Nobel lecture: “I thought I was finding out what Dirac meant, bu
t, as a matter of fact, had made the discovery that what Dirac thought was analogous, was, in fact, equal” (NL, 10). Schwinger, however, in a tribute delivered at a memorial service to Feynman, made a subtle point of dismissing the possibility that Dirac might not have understood the implications of his paper: “Now, we know, and Dirac surely knew, that to a constant factor the ‘correspondence’ … is an equality…. Why, then, did Dirac not make a more precise, if less general, statement? Because he was interested only in a general question.” Schwinger 1989, 45.
226 OPPENHEIMER HAD INVITED HIM: Feynman to Oppenheimer, 5 November 1946, CIT
226 THE CHAIRMAN OF THE UNIVERSITY OF PENNSYLVANIA’S PHYSICS DEPARTMENT: G. P. Harnwell to Bethe, 25 February 1947, and Bethe to Harnwell, 4 March 1947, BET.

228 I AM FEYNMAN: Pais 1986, 23.
229 SPIN WAS A PROBLEM: Schweber 1986a, 469.
229 NO WONDER HIS EYE: “Within a week, altogether, this question of the rotation [of the plate] started me worrying about rotations, and then old questions about the spinning electron, and how to represent it in the path integrals and in the quantum mechanics, and I was in my work again. It just opened the gate.” F-W, 430.
230 FEYNMAN DID NOT ATTEMPT TO PUBLISH: F-W, 444.
230 THE CHALLENGE WAS TO EXTEND: Ibid., 443; Schweber 1986a, 472.

234 THE FACTS WERE INCREDIBLE: Quoted in Schweber, forthcoming.

234 DEBACLE: Polkinghome 1989, 12.
235 IT WAS HARDLY A COMMON NAME: Morrison, interview.

239 HE HAS DEVELOPED A PRIVATE VERSION: Ibid.
239 HE TELEPHONED FEYNMAN: NL, 449.
239 IT WAS A BLUNT LOS ALAMOS-STYLE ESTIMATE: It diverged, but it only diverged logarithmically, heading ever higher, but ever more slowly, like the series 1 + ½ + 1/3 + ¼ + …—after a million terms this has not even reached 15, but it never does stop rising. When the news reached Russia, the great Lev Landau said with obscure Slavic wisdom, “A chicken is not a bird, and a logarithm is not infinity.” Weinberg 1977a, 30; Sakharov 1990, 84.
239 BUT THEY DID NOT COINCIDE: Bethe, interview.

249 HE LATER FELT THAT HE WAS BETTER KNOWN: Kac 1985, 115–16.

252 I DID IT TOO, DADDY: F-W, 463–64.
252 I’M SO SORRY: Rose McSherry to Feynman, 21 January, 1948, PERS.
253 MONTHS PASSED BEFORE
FEYNMAN CALLED: Feynman formally acknowledged the error in a footnote to a paper published the next year; he juggled the footnotes so that the apology would fall in number 13: “That the result… was in error was repeatedly pointed out to the author, in private communication, by V. F. Weisskopf and J. B. French…. The author feels unhappily responsible for the very considerable delay in the publication of French’s result occasioned by this error.” Feynman 1949b, 777; Weisskopf, interview; Weisskopf 1991, 168.
253 A HOLE IF THERE WERE ONE: Dirac in Proceedings of the Royal Society of London A 133(1931):60.

258 BOHR CONTINUED FOR LONG MINUTES: F-W, 473; cf. Pais 1986, 459, but this conflates Teller’s and Bohr’s objections.

258 ON HIS FIRST DAY BACK: Arthur Wightman, interview, Princeton, N.J.
259 YOU CAN IMAGINE THAT I WAS HIGHLY PLEASED: Quoted in Schweber, forthcoming. 259 ANONYMOUSLY, HE HOPED: Feynman 1948e, 9.
