Julius and Ethel Rosenberg. Ethel Greenglass Rosenberg (September 28, 1915 â June 19, 1953) and Julius Rosenberg (May 12, 1918 â June 19, 1953) were American communists who were convicted and executed in 1953 for conspiracy to commit espionage during a time of war.
The Rosenbergs were the last people in the U.S. involved in a treason trial to be convicted, sentenced to death, and then executed. Their execution in 1953 was debated globally and was seen as an important development in the Cold War and the expansion of the era of McCarthyism.
