Cairncross worked as private secretary to Sir Maurice Hankey, a high-ranking British official involved with Tube Alloys, the secret British atomic program during World War II. In this position, he gave Moscow a listof American atomic scientists and may have leaked information about a report evaluating Britain’s prospects of building a uranium bomb ...
The Soviet Union’s longest-serving spy in Britain, Norwood worked as a secretary for a director of the Tube Alloys project. While living an apparently normal life in the London suburbs, she passed information to Soviet agents throughout the war—and into the 1970s. It’s unclear how much Norwood’s espionage helped the Soviet atomic program, but she w...
Fuchs, a German-born physicist, fled to England amid the rise of Nazism in 1933 and became a British citizen in 1942. By that time, he had already offered to spy for the Soviets. In late 1943, Fuchs joined a group of British scientists who traveled to Los Alamos to work for the Manhattan Project, and he later passed key information about atomic wea...
Gold in turn named David Greenglass, a U.S. Army machinist who had worked at the classified nuclear facility at Oak Ridge, Tennessee before being assigned to Los Alamos in 1944. Recruited to spy for the Soviets by his brother-in-law, Julius Rosenberg, Greenglass passed information to the Soviets in mid-1945 that included a hand-drawn sketch and not...
McNutt was a civil engineer in New York City and a friend of Julius Rosenberg, who in late 1943 encouraged him to get a job at Kellex, a company building the massive gaseous diffusion plant to separate uranium at Oak Ridge. Rosenberg connected McNutt to the KGB, the Soviet security agency. Though he gave the Soviets the plant's design, McNutt (desp...
Hiskey, a chemist, began working on gaseous diffusion at Columbia University and was later transferred to Chicago’s Metallurgical Laboratory (Met Lab), another key part of the Manhattan Project. Hiskey passed information to the GRU, or Soviet military intelligence, rather than the KGB. After he was seen meeting with the known Soviet agent Arthur Ad...
The release of the decrypted Venona intercepts in the mid-1990s revealed that Theodore Hall, the youngest physicist on the Manhattan Project, was the long-suspected third spy (after Fuchs and Greenglass) at Los Alamos. Codenamed “Mlad,” Hall had reached out to the Soviets in late 1944 and soon after provided them with a key update on the developmen...
In 2019, after searching through recently declassified FBI files, Klehr and John Earl Haynes reported the existence of a fourth Soviet spy at Los Alamos. Oscar Seborer, codenamed “Godsend,” was the son of Jewish immigrants from Poland who became an electrical engineer and worked at Los Alamos from 1944-46. Though it’s still unknown exactly what inf...
