Julius Rosenberg (May 12, 1918-June 19, 1953) and Ethel Greenglass Rosenberg (September 25, 1915-June 19, 1953) were an American couple that were charged with high treason against the U. S. government. They were tried for allegedly being spies for the Soviet Union, and they were also believed to have been passing crucial information about the atomic bomb over to the Soviets. They were found guilty of all charges, and were sentenced to death. On June 19, 1953, they were sent to the electric chair, and they were electrocuted at dawn by New York executioner Joseph Francel.
After their executions, many Americana citizens criticized the government for deciding to send those two to death without any exact evidence to prove that they were guilty of all charges. This criticism was understandable, because the U. S. was at the time engaged in the Cold War with the Soviet Union, and they were deathly paranoid about the Soviets and their government. However, in 1995, the U. S. government ran several Soviet cables, which were decoded, and they revealed Julius' involvement with the Soviet Union, thus proving his guilt. However, it's unknown how much his wife knew about her husband's dealing with the Soviets, nor is it currently known if she ever helped them in their cause.
