28. The Spy Who Betrayed Oppenheimer: The Manhattan Project (Ep 2)

What makes a man betray his closest friends? How did a German refugee help Stalin build the bomb? And why did British intelligence fail to spot the most dangerous spy in the Manhattan Project? Klaus Fuchs was brilliant, quiet, and unassuming. A physicist at the cutting edge of nuclear science, he worked at the heart of Britain’s secret atomic weapons program before being sent to the United States to join the Manhattan Project. But, all the while, Fuchs was passing the most closely guarded secrets of the West straight to the Soviet Union. Listen as David and Gordon uncover how Fuchs’ communist beliefs and wartime alliances led him to become one of the most infamous spies of the 20th century. ------------------- Order a signed edition of David's latest book, The Seventh Floor, via this link. ------------------- Get our exclusive NordVPN deal here ➼ www.nordvpn.com/restisclassified It’s risk-free with Nord’s 30-day money-back guarantee!
