From The Archives: The Rosenberg Executions

Julius Rosenberg in a police van in New York after his arrest in 1950. A longtime communist supporter, he was reportedly recruited as a spy by the Soviet NKVD during his U.S. Army service in World War II.

FBI agents lead Julius Rosenberg away shortly after his arrest. His wife's brother, David Greenglass, had confessed to participating in a spy ring that he said included the Rosenbergs.

Later evidence emerged that Julius Rosenberg had in fact acted as a courier and recruiter for Soviet intelligence. But the involvement of Ethel Rosenberg, seen here in an undated photo, was more ambiguous, and may have involved little more than typing notes for Julius.

The case helped fuel the anticommunist investigations of the 1950s in the United States. Julius Rosenberg said, "There had to be a Rosenberg case because there had to be an intensification of the hysteria in America to make the Korean War acceptable to the American people."
