Sleeper Agent: The Atomic Spy in America Who Got Away by Ann Hagedorn (HC/DJ) *This copy not Ex-Library as pictured.
Born in Iowa, schooled in science at Columbia University, and as American as baseball, George Koval was the ultimate secret agent. Because he had security clearances to the Manhattan Project, he was able to pass invaluable classified information that helped Soviet scientists produce an atomic bomb years earlier than US experts had expected. The FBI only identified him several years after he had returned to the Soviet Union, and in 2007, Vladimir Putin posthumously awarded him Russia’s highest civilian honor for his contribution to the Soviet atomic bomb program.
