Rosenbergs convicted of espionage

On March 29, 1951, American citizens Julius and Ethel Rosenberg were convicted and sentenced to death for conspiracy to commit espionage for the Soviet Union. From the article:

"Rosenbergs convicted of espionage
In one of the most sensational trials in American history, Julius and Ethel Rosenberg are convicted of espionage for their role in passing atomic secrets to the Soviets during and after World War II. The husband and wife were later sentenced to death and were executed in 1953.

The conviction of the Rosenbergs was the climax of a fast-paced series of events that were set in motion with the arrest of British physicist Klaus Fuchs in Great Britain in February 1950. British authorities, with assistance from the U.S. Federal Bureau of Investigation, gathered evidence that Fuchs, who worked on developing the atomic bomb both in England and the United States during World War II, had passed top-secret information to the Soviet Union. Fuchs almost immediately confessed his role and began a series of accusations.

Fuchs confessed that American Harry Gold had served as a courier for the Soviet agents to whom Fuchs passed along his information. American authorities captured Gold, who thereupon pointed the finger at David Greenglass, a young man who worked at the laboratory where the atomic bomb had been developed. Gold claimed Greenglass was even more heavily involved in spying than Fuchs. Upon his arrest, Greenglass readily confessed and then accused his sister and brother-in-law, Ethel and Julius Rosenberg, of being the spies who controlled the entire operation. Both Ethel and Julius had strong leftist leanings and had been heavily involved in labor and political issues in the United States during the late-1930s and 1940s. Julius was arrested in July and Ethel in August 1950.

By present-day standards, the trial was remarkably fast. It began on March 6, and the jury had convicted both of conspiracy to commit espionage by March 29. The Rosenbergs were not helped by a defense that many at the time, and since, have labeled incompetent. More harmful, however, was the testimony of Greenglass and Gold. Greenglass declared that Julius Rosenberg had set up a meeting during which Greenglass passed the plans for the atomic bomb to Gold. Gold supported Greenglass’s accusation and admitted that he then passed the plans along to a Soviet agent. This testimony sealed Julius’s fate, and although there was little evidence directly tying Ethel to the crime, prosecutors claimed that she was the brain behind the whole scheme. The jury found both guilty. A few days later, the Rosenbergs were sentenced to death. They were executed on June 19, 1953 in Sing Sing Prison in New York. Both maintained their innocence to the end.

The Rosenberg case garnered worldwide attention. Their supporters claimed they were being made scapegoats to the Cold War hysteria that was sweeping America. The French writer and philosopher Jean-Paul Sartre called their execution a “legal lynching.” Others pointed out that even if the Rosenbergs did pass secrets along to the Soviets during World War II, Russia had been an ally, not an enemy, of the United States at the time. Those who supported the verdict insisted that the couple got what they deserved for endangering national security by giving top-secret information on a devastating weapon to communists."
