Lewis Strauss–William L. Borden alliance

The alliance between Lewis Strauss and William L. Borden turned suspicions about J. Robert Oppenheimer into a coordinated effort to assemble a case against him. Strauss supplied access and institutional leverage; Borden, drawing on Oppenheimer’s security file, shaped the material into a concise accusation. Their work joined a dispute over nuclear policy to the machinery of security investigation, placing Oppenheimer’s political associations and professional judgments under suspicion together.

Shared Suspicions and Political Stakes

During the Eisenhower transition, Strauss remained in contact with Borden, then the young staff director of the Joint Committee on Atomic Energy. Borden had lost that post after Republicans gained control of the Senate, but his preoccupation with Oppenheimer continued. He prepared a sixty-five-page report tracing the physicist’s influence in Washington and emphasizing the range of officials, policy questions, and foreign visitors with whom Oppenheimer had recently dealt. The report portrayed not simply a prominent scientist, but a man whose expertise and reputation gave him access to discussions of atomic power, foreign policy, bombing strategy, international control, and weapons development.

Strauss shared Borden’s suspicions and had encouraged his inquiries. Their concern was inseparable from the conflict over the hydrogen bomb. In a four-page letter to Borden in December 1952, Strauss argued that development of the weapon had been delayed by three years. He blamed the General Advisory Committee for dragging its feet and pointed to Soviet espionage as a reason not to assume that the United States held a lead. Strauss and Borden both regarded Oppenheimer as substantially responsible for the dangerous position they believed the country had reached. Their alliance thus took shape around an interpretation that made policy disagreement and security suspicion reinforce one another.

Borden’s report also conveyed why Oppenheimer seemed politically consequential to his critics. It itemized a week in which he had met corporate, military, diplomatic, and political figures, including the Secretary of State and the two 1952 presidential candidates. Borden presented Oppenheimer’s powers of persuasion and standing among scientists as sources of influence, not merely professional distinction. The portrait made his public role itself part of the case: the more access and authority he possessed, the more urgent his critics could represent scrutiny as necessary.

Access to the Security File

In late April 1953, Borden visited Strauss’s office to discuss their shared concerns. According to the account cited in the book, Borden handed Strauss a mysterious document, probably a compilation of his suspicions; it has never been found. The surviving record does not establish precisely what the two men agreed in that meeting. Their subsequent actions, however, support the book’s interpretation that they settled on a plan to end Oppenheimer’s influence, with Borden assembling the case and Strauss facilitating access to the information required for it.

Within two weeks, Borden received permission to check Oppenheimer’s security file out of the Atomic Energy Commission’s security vault. Although Borden left his government position on May 31, he retained the file until August 18. On July 16, while Borden was reading it at a vacation retreat in upstate New York, Strauss spoke with him by telephone. Within hours of the file’s return, it was on Strauss’s desk. Strauss kept it for nearly three months, returning it to the vault on November 4. A few hours later, Bryan F. LaPlante, an AEC assistant security officer and Strauss confidant, checked it out and held it until December 1.

The sequence of withdrawals and returns is central to the account of the alliance. The book judges that the transfers were coordinated rather than coincidental: Borden had the file while preparing his indictment; Strauss obtained it after Borden returned it; then LaPlante reviewed it. The record supports a pattern of access and cooperation, even as the precise contents of the missing document and the terms of the April conversation remain unknown. By the time Strauss formally became AEC chairman in July, he was also studying the FBI’s latest summary of Oppenheimer, which ran to sixty-nine single-spaced pages. The inquiry drew on a much larger surveillance file and on records held within the agencies whose authority Strauss could mobilize.

From Investigation to Accusation

After losing his committee post, Borden found work in Pittsburgh with Westinghouse’s nuclear submarine program. He continued investigating Oppenheimer in the evenings, using the top-secret AEC personnel file Strauss had helped him obtain. By mid-October, Borden had drafted a letter that distilled his conclusions into three and a half single-spaced pages. He sent it to J. Edgar Hoover on November 7.

The letter combined evidence of Oppenheimer’s Communist associations with an account of his recommendations on nuclear weapons. Borden concluded that Oppenheimer was more likely than not an agent of the Soviet Union. This was not a neutral summary of a file: it transformed a collection of political connections and policy judgments into a direct allegation of espionage. The compact form sharpened the effect. Material that had been lengthy and convoluted in FBI summaries became, in Borden’s hands, a focused prosecution-style brief.

Strauss’s role in the letter’s circulation is documented less directly. Hoover forwarded it to Strauss, the Secretary of Defense, and the president on November 27. A November 9 note Strauss wrote for his files suggests that he may already have read the completed letter, although the precise timing of his knowledge is not established. By November 30, Strauss was identifying the Chevalier affair as the key issue: how long after the episode Oppenheimer reported it to Leslie Groves, and whether Oppenheimer knew Groves had learned of it before making his report. The book notes that there was no evidence Groves knew of the conversation before Oppenheimer told him, and that Groves’s testimony supported this point. Strauss’s focus nevertheless helped make the disputed accounts of that episode central to the developing case.

Coordination and Consequences

The alliance operated through complementary roles rather than through a single public declaration of purpose. Borden researched, selected, and framed the evidence; Strauss enabled access to the file, studied it, and occupied a position from which the accusation could reach senior officials. In July 1953, according to AEC staff lawyer Harold Green, Strauss had promised Hoover that he would purge Oppenheimer. That reported promise gives the sequence a stated objective, while the file transfers and Borden’s letter show the practical work undertaken toward it.

The effort exploited the ambiguity between political dissent and disloyalty. Oppenheimer had challenged proposals for nuclear warfare and had exercised influence in Washington; his critics joined those facts to earlier political associations and the contradictions surrounding the Chevalier affair. Borden’s allegation that he was a Soviet agent went well beyond describing disagreement or access. The alliance helped turn those separate elements into an indictment that could be used against him in the security process. Its significance lies both in the personal attack it prepared and in the institutional method it illustrates: confidential records, surveillance-derived material, and policy disputes could be assembled into a case capable of silencing a prominent critic.
