Cohn was famous — and infamous — for his work for Sen. Joseph McCarthy of Wisconsin in the 1950s investigating suspected infilitration by communists in U.S. government agencies, as well as his role prosecuting Soviet spies Julius and Ethel Rosenberg, who were executed for stealing American atomic secrets.In the Rosenberg case, Cohn later admitted to conversations with the trial judge outside of the presence of the Rosenberg lawyers — a serious ethical breach by both Cohn and the judge.(English)
