NKVD

The NKVD appears in the account as a Soviet intelligence service seeking access to the American atomic-bomb project, but its surviving records do not substantiate the later claim that J. Robert Oppenheimer became its source. The contrast between an agent’s self-protective assertion and documents describing Oppenheimer as a prospective, still-unrecruited target makes the limits and competing interests of intelligence archives central to the organization’s portrayal.

Wartime Interest in Oppenheimer

A small number of documents from Soviet archives indicate that the NKVD knew Oppenheimer was working on Enormoz, its code name for the Manhattan Project. NKVD officials regarded him as a potentially sympathetic fellow traveler, perhaps even a secret member of the American Communist Party, and were frustrated that he seemed difficult to approach. Their interest did not mean they had secured his cooperation: a separate record describes plans for cultivation as something conditional on whether the GRU succeeded in recruiting him first.

The Merkulov Claim and Its Provenance

In an October 1944 memorandum to Lavrenty Beria, NKVD deputy chief Vselovod Merkulov claimed that Oppenheimer had informed the Soviets about the beginning of American uranium work in 1942 and helped provide access to research through tested sources. The account identifies no corroborating evidence for these assertions and notes that there is no evidence Grigory Kheifets, the NKVD agent stationed in San Francisco, ever met Oppenheimer. The memorandum is therefore presented not as proof of a successful recruitment, but as a claim whose origin and purpose require scrutiny.

The circumstances give the claim a possible bureaucratic motive. Kheifets had been recalled to Moscow in the summer of 1944 for inactivity and faced accusations that he might be a double agent. By claiming to have developed Oppenheimer as a source, he could bolster his record and protect his position—and, the account concludes, his life. The file’s most sensational assertion thus appears entangled with the agent’s own peril rather than independently verified intelligence.

Evidence Against Recruitment

Notes taken in the Soviet archives by former KGB agent Alexander Vassiliev record a February 1944 message stating that Oppenheimer had been cultivated by the GRU since June 1942. The message instructs the NKVD to seek him only if that recruitment did not succeed, and otherwise to obtain the GRU’s materials on him and begin cultivation through its own channels. This account directly conflicts with Merkulov’s later representation of Oppenheimer as an established source. It indicates that, as of early 1944, the NKVD had not recruited him as an informant, agent, or spy.

The practical setting reinforces that distinction. By 1944 Oppenheimer was living behind barbed wire at Los Alamos, under round-the-clock surveillance by Leslie Groves and U.S. Army counterintelligence. The available evidence therefore supports a narrower conclusion than the dramatic memorandum: the NKVD watched for a possible opening and considered how to cultivate Oppenheimer, but the records cited do not show that it gained his services or received atomic information from him.
