Ethel Greenglass Rosenberg was born September 28, 1915 in New York City and was the only daughter out of four children, and was a determined and bright young girl. After graduating from Seward Park High School at the young age of 15, Ethel went to work as a clerk for a shipping company. After arranging a strike that consisted of 150 women workers Ethel was let go from the company. Ethel had a great interest in politics and joined both the Young Communist League and the American Communist Party.
In 1939 Ethel married a man by the name of Julius Rosenberg. Soon after they were married Ethel's health forced her to quit working and as a result she became a stay at home mom, watching over her two sons Michael and Robert.
In 1950 her younger brother David Greenglass named her husband Julius as a participant in the spy ring, and he was placed under arrest. Soon after on August 11, 1950 Ethel was arrested as well, and at the trial her sister in law, Ruth Greenglass testified against Ethel claiming that she had been involved in the atomic spy ring. Both she and her husband were found guilty of espionage and were sentenced to death on April 5, 1951. Ethel Rosenberg spent the next two years of her life at Sing Sing prison, and on June 19, 1953, Ethel was put to death in the electric chair.
