Mid-20th century Soviet spies

In August 1950, Julius and Ethel Rosenberg were indicted under Title 50, sections 32a and 34, in connection with giving nuclear secrets to the Soviet Union. Anatoli Yakovlev was indicted as well. In 1951, Morton Sobell and David Greenglass were indicted. After a controversial trial in 1951, the Rosenbergs were sentenced to death. They were executed in 1953. In the late 1950s, several members of the Soble spy ring, including Robert Soblen, and Jack and Myra Soble, were prosecuted for espionage. In the mid-1960s, the act was used against James Mintkenbaugh and Robert Lee Johnson, who sold information to the Soviets while working for the U.S. Army in Berlin.
