Berman to Committee on Un-American Activities,” Sept. 20, 1948, Louise Berman papers, State Historical Society of Wisconsin, Madison, Wis. Louise married Lionel Berman in 1947 and changed her name.
65. Richard Bransten was heir to the MJB coffee-importing business founded by Morris J. Brandenstein. Bransten later became a successful Hollywood scriptwriter, providing financial backing to the magazine New Masses. Bransten had been the subject of an FBI investigation since 1941. Summary report, n.d., 444–45, pt. 6, Silvermaster file, FBI.

In Nov. 1945, the FBI obtained a copy of a lengthy autobiography that Bransten had prepared for Mikhail Vavilov, then the Soviet consul in San Francisco. Preparation of such an autobiography was one of the final steps in the recruitment of an agent. Summary report, Apr. 22, 1947, COMRAP file, FBI.
67. San Francisco field report, May 31, 1944, sec. 44, COMRAP file, FBI.
68. Bransten’s Rosenberg Foundation also bankrolled the publication and distribution to Bay Area schools of a children’s book that Dolly had written while in Russia, The Boy from Leningrad.

71. Interviews: King and Bowser (1997). A May 1943 FBI report, noting the “illicit relationships” between Bransten and Kheifets, concluded, “These possibilities will be borne in mind in future investigations.” San Francisco field report, May 7, 1943, vol. 1, Nelson file, FBI.
72. Jerrold and Leona Schecter, Sacred Secrets: How Soviet Intelligence Operations Changed American History (Brassey’s, 2002), uncorrected page proofs, 47–50, 315–16. In their previous book, written in collaboration with Soviet spymaster Pavel Sudaplatov, the authors had claimed that Oppenheimer also informed Kheifets that American atomic scientists “were planning to move from Berkeley, California, to a new site to conduct research in nuclear weapons.” In Dec. 1941, of course, neither the Met Lab at Chicago nor the laboratory at Los Alamos could have been discussed by Oppenheimer or anyone else. Sudaplatov et al. (1994), 174–75.
73. In the winter of 1942–43, the Chevaliers hosted another party for Russian war relief which Robert and Kitty Oppenheimer attended. “And of course the Soviet consulate was represented.” Chevalier (1965), 51.

89. The transcript of the Nelson-“Joe” conversation, without date or title, was kept by Groves in his personal safe during the war. Transcript, entry 8, box 100, MED/NARA. Excerpts are also in a memo of Aug. 19, 1949, Joseph Weinberg FBI file, box 6, JRO/AEC.
90. Doyle was the organizational secretary of the Communist Party in Alameda County. She and Nelson had met with Joe the previous Thursday, Mar. 25. Glavin to Tolson, Sept. 29, 1948, 50, HUAC file, FBI.
91. Transcript, entry 8, box 100, MED/NARA. “Joe dictated and Steve wrote down at this point approximately 150 to 200 words, largely indistinguishable, but believed to be from the conversation a basic formula of some type,” Branigan noted. The “magnetic spectrograph” was Lawrence’s Calutron. The “velocity selector” referred either to the Isotron or to an apparatus used by Nelson and Frankel in measuring uranium cross sections. A 5-centimeter sphere may have referred to the critical-mass calculations performed by Nelson and Frankel; the plutonium core of the first atomic bomb would have made a solid sphere approximately 5.5 centimeters in diameter. The mention of deuterium suggests that “Joe” might also have passed along information about the 1942 summer seminar that discussed the Super, since deuterium plays no role in electromagnetic separation. David Hawkins, Project Y: The Los Alamos Story (Tomash Publishers, 1983), pt. 1, 99–100; transcript, entry 8, box 100, MED/NARA; personal communications: Herbert York, Nov. 5, 1997; Eldred Nelson, Jan. 25, 1998.
92. Ironically, Nelson told Joe that he and his friends “should never talk in a house but only when they were outside.” Nelson-“Joe” transcript, 26.
93. King interview (1997).
94. Coincidentally, Nelson’s meeting with “Joe” occurred just a week after the FBI and the FCC discovered the secret radio transmitter at San Francisco’s Soviet consulate. See note 35.

97. Zubilin’s real name was Zarubin, his code name Maxim; both he and his wife, Elizabeth (code names Vardo and Helen), were senior NKVD agents. Zubilins: Haynes and Klehr (1999), 394; Robert Louis Benson, Venona Historical Monograph, no. 2 (U.S. National Security Agency, 1996), 4–6; Benson and Warner (1996), 51–54.
98. A 1952 publication by the House Committee on Un-American Activities contained a slightly different version of this conversation. U.S. Congress, The Shameful Years: Thirty Years of Soviet Espionage in the United States (U.S. Government Printing Office, 1952), 31. The version here is taken from verbatim transcripts contained in two contemporaneous FBI reports on Nelson. Ladd to Hoover, Apr. 16, 1943, 1–9, vol. 2; and San Francisco field report, May 7, 1943, 10–22, vol. 1, Nelson file, FBI.
99. Nelson has been suggested as a candidate for a still-unidentified West Coast Soviet operative who appears in Venona messages, code-named Butcher. Nelson’s real name, Mesarosh, means “meat-cutter” in Hungarian. Haynes and Klehr (1999), 428 fn.
100. Although “Bernstein” is deleted from the transcript in most of the FBI’s report, a subsequent analysis of the Nelson-Zubilin conversation by the bureau notes a reference by Nelson to “the Bernstein woman,” whom the bureau concluded was Louise Branst

103. “Under no circumstances should this matter be discussed at conferences with representatives of G-2 and ONI [Office of Naval Intelligence],” the FBI director instructed. Hoover to SACs, Apr. 9, 1943, sec. 1, CINRAD file, FBI.
104. The Hoover-Hopkins memo is cited in Benson and Warner (1996), 49–50. It is unclear whether Hopkins ever responded to Hoover’s warning. However, Robert King remembered Pieper telling him that the reaction from the White House had been simply, “Do nothing to embarrass our ally.” King interview (1997).
105. Lansdale to Strong, Apr. 5, 1943, “DSM Project” folder, box 2, Pash papers.

111. DeSilva: Davis (1968), 188–89; Hoddeson et al. (1993), 96. Pash and de Silva found the instructions puzzling; Lansdale seemed to be suggesting that they not scrutinize Oppenheimer too closely. Lansdale to Pash, Mar. 13, 1943, box 1, JRO/AEC.
112. Hoover’s Mar. 1943 letter to General Strong wrongly asserted that Lomanitz had been present in the meeting with Nelson and volunteered to commit espionage.
113. Lomanitz interview (1996).
114. De Silva to Lansdale, June 12, 1943, box 3, JRO/AEC.
115. Weinberg to “Opje,” Apr. 12, 1943, box 77, JRO. Technically, Weinberg’s conversation with Nelson in late March may not have violated the security act, since Weinberg filled out the OSRD’s personnel security questionnaire on Apr. 14, 1943, and was put on the Rad Lab payroll on Apr. 27. Marshall to Groves, July 24, 1943, entry 8, box 100, MED/NARA. When Nelson asked whether any experiments had yet been conducted, Joe’s answer indicates that his friends were still being tight-lipped: “Joe stated that he did not know, that he had asked his friends the results of the tests but that they had refused to say, these friends feeling that possession of the knowledge was extremely dangerous.” Transcript, entry 8, box 100, MED/NARA.
116. Eldred Nelson interview (1997).
117. Hoover to Strong, June 22, 1943, sec. 4, CINRAD file, FBI.
118. They were, observed one reader of the transcripts, “the most boring conversations imaginable.” Weinberg folder, CINRAD file, FBI. My thanks to Stan Norris for copies of CINRAD documents on the investigation of Weinberg and his family.
119. Weinberg’s Rad Lab personnel file contained this notation by a security agent, quoting Birge: “Oppenheimer knows all about this man. If he wants W. it is his decision.” Marshall to Groves, July 24, 1943, entry 8, box 100, MED/NARA.

34. King interview (1997).
35. The Aug. 7 letter was probably written by Lieutenant Colonel Mironov of the NKVD, an aide to Zubilin. Mironov was subsequently recalled and confined to a mental institution in the Soviet Union.

54. Groves may have wanted to draft Lomanitz so that Rossi could later be court-martialed.
