These walls of water can cause widespread destruction when they crash ashore.hotograph by Deshakalyan Chowdhury/AFP/Getty Images.

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 problem of a weak case against Ethel Rosenberg was solved just ten days before the start of the trial when David and Ruth Greenglass were reinterviewed. They were persuaded to change their original stories. David had said that he'd passed the atomic data he'd collected to Julius on a New York street corner.
