The Man Who Would Be God

The Man Who Would Be God is Haakon Chevalier’s thinly disguised novel about a brilliant physicist building an atomic bomb who becomes the de facto leader of a Communist Party closed unit. Its significance lies not only in its fictional portrait of J. Robert Oppenheimer, but in the long argument over how to describe their political association: Chevalier used a novel to suggest a degree of Communist commitment that Oppenheimer denied, then later recast the claim as memoir.

Origins and publication

In 1948, Chevalier outlined a novel whose central figure combined the work of a physicist building an atomic bomb with leadership of a closed unit of the Communist Party. He began a manuscript, but set it aside in 1950 after he could not find a publisher. Following Oppenheimer’s 1954 security hearing, Chevalier returned to the project. G. P. Putnam’s Sons published it in 1959 under the deliberately weighty title The Man Who Would Be God.

The delay matters to the book’s position between fiction and political testimony. Chevalier had described Oppenheimer as a left-wing intellectual who was not under Party discipline, yet the novel gave its physicist alter ego a more organized role inside Communist life. Rather than simply reproduce the earlier account of their friendship, the book shaped that friendship into a fictional structure in which political involvement was central to the protagonist’s identity.

Sebastian Bloch and the closed unit

The physicist in the novel is Sebastian Bloch, who decides to join the Communist Party. The local Party leader, however, refuses to admit him formally. Bloch instead meets regularly with the unit and is treated by its members as a bona fide member, while paying no dues and making any financial arrangements with the party outside the unit. The arrangement makes his status deliberately equivocal: he belongs in practice and in the eyes of others, but not through formal enrollment.

Chevalier presents the unit’s weekly gatherings less as secretive political rituals than as campus intellectual life. He calls them “informal seminars of the kind that were constantly being held on all sorts of subjects among professors and students on the campus.” Members discuss ideas and theory, current events, a Teachers’ Union member’s activity, and support for labor campaigns, strikes, or people facing civil-liberties attacks. The novel thus places political work within familiar academic and civic discussion, while still defining the group as a Communist Party unit.

The distinction between informal discussion and organized affiliation also appears in the episode prompted by the Soviet Union’s invasion of Finland in November 1939. Chevalier’s Oppenheimer-like character proposes that the unit publish essays explaining international events “in language palatable to cultivated, critical minds.” He pays the printing and postage costs and does most of the writing. Chevalier calls the project “his baby”; several “Reports to the Faculty” appear over the following months. In the novel, Bloch’s political engagement therefore takes a practical form: he helps shape arguments for an educated readership and personally funds their circulation.

Reception and the return to memoir

The novel sold poorly, and Chevalier disliked the reviews. A reviewer for Time magazine judged that its “novel’s underlying tone suggests an ex-worshipper stomping on a fallen idol.” The response captured a problem Chevalier later acknowledged: readers were disturbed by the mixture of truth and fiction. The novel could register his interpretation of the friendship, but its fictional form also made the boundary between remembered events and invented presentation difficult to assess.

In the summer of 1964, Chevalier wrote to Oppenheimer that he had nearly finished a memoir about their friendship. He said he had tried to tell the essential story in the novel, but now wanted to tell it straight, particularly the story of their supposed membership in the same Communist Party unit from 1938 to 1942. Chevalier described Oppenheimer’s commitment as deep and genuine and argued that it deserved prominence. He asked whether Oppenheimer objected to his telling that story. Oppenheimer’s reply was a terse note; Chevalier reasonably understood the denial as a warning that a claim of Party membership could expose him to a libel suit.

The following year, Chevalier published Oppenheimer: The Story of a Friendship without the direct allegation that Oppenheimer had joined the Communist Party. Across the book, the alleged closed unit became a “discussion group.” The shift did not erase the dispute; it changed the terms in which Chevalier could present it. The novel’s fictional Sebastian Bloch had made the contested affiliation part of a character’s story, while the later memoir avoided stating it as an unqualified fact.

The disputed meaning of political association

The evidence surrounding the novel leaves two accounts in tension. Chevalier believed the Berkeley discussion group’s members belonged to the Communist Party. Oppenheimer insisted that he did not. He gave money to particular causes, including the Spanish Republic, farm workers, civil rights, and consumer protection; attended meetings; offered advice; and helped Party intellectuals write position papers. But he had no Party card, paid no dues, and was free of Party discipline. His friends could regard him as a comrade even as he understood himself not to be one.

That distinction clarifies what the novel’s premise both asserts and blurs. Its central character’s informal standing, the unit’s seminar-like meetings, and his public-facing political writing all resemble forms of participation described in accounts of Oppenheimer’s Berkeley years. But resemblance does not settle the question of formal membership. The book preserves Chevalier’s conviction by turning it into fiction; its later revision into memoir shows how strongly the same conviction continued to press against Oppenheimer’s denial. The result is not a definitive record of their political relationship, but a revealing account of how friendship, memory, and disputed affiliation became material for competing narratives.
