VENONA and the Rosenbergs

The Museum display includes photographs of American citizens who gave information to the Soviet KGB, replicas of the messages revealing the espionage, and some World War II-era artifacts similar to those used by KGB officers. The Rosenbergs case was controversial, partly due to the accusation and conviction of Ethel Rosenberg. VENONA messages indicate that her husband, Julius, was heavily involved in providing information to his KGB handler. At least one message shows that Ethel may have known about her husband's activities. Ethel's brother, David Greenglass, was also involved, selling details about the atomic bomb project in Los Alamos where he worked. It was David's testimony against his sister and brother-in-law that led to the conviction of the Rosenbergs for conspiracy to commit espionage.
