Julius and Ethel Greenglass Rosenberg were a married couple from New York City. Of Jewish-American origin, the two had met in 1936 at a meeting of the Young Communist League.
Julius joined in the army in 1940, where he served in the Signal Corps, working on radar equipment. He was recruited by the NKVD as a spy in 1942, and passed a considerable body of data to the Soviets, notably the proximity fuse used to shoot down Gary Powers in 1960.
But with the arrest of Klaus Fuchs at Los Alamos, the dominoes started to fall. Fuchs fingered another spy: his courier, Gold. Gold has also been a courier for David Greenglass – Ethel’s brother. Greenglass testified that he had been recruited by Julius, though he denied Ethel’s involvement.
The Rosenbergs were convicted on March 29, 1951, and sentenced to death on April 5. The conviction helped to fuel Senator Joseph McCarthy’s investigations into anti-American activities by U.S. citizens. While their devotion to the Communist cause was well-documented, the Rosenbergs denied the espionage charges even as they faced the electric chair. They were the only two American civilians to be executed for espionage-related activity during the Cold War.
