16. The Rosenbergs

Julius and Ethel Rosenberg started out like any other American couple, but their betrayal made history.

The Rosenbergs were implicated by Ethel’s brother in a double betrayal. He testified against them in court and was offered a ten year prison sentence in return. Despite public outcry, the Rosenbergs were sentenced to die by electrocution.
