Poker George Koval (1913-2006)
United States and the USSR were allies during World War II. Or so they said. The truth is that the Soviet secret services had about a dozen spies working on the Manhattan Project . Ie they had almost real time information about scientific advances that were trying to develop the bomb. George Koval (codename DELMAR) was in charge of controlling the radiation present in Los Alamos and had access to any agency. Was learned that U.S. spy in 2007, when Vladimir Putin awarded him posthumously. Ironic, right?
Seal honor of Morris Cohen (1910-1995)
Morris Cohen (known in England as Peter Kroger) was a volunteer in the English Civil War on the Republican side and was also part of the U.S. military in World War II. He was the liaison between Theodore Hall, a spy who worked at Los Alamos, and the secret services in Moscow. He settled in London in 1951 (where he continued spying on the British army) and was discovered and arrested. In 1969 he was exchanged for a captured British spy in the USSR. If you have your face on a Russian label is because it was decorated for his "services."

The case of David Greenglass
