You’d think the guy helping build the deadliest weapon in history would be someone the Allies vetted carefully. You’d be wrong. Klaus Fuchs was a physicist, a refugee, and a trusted member of the Manhattan Project. He was also a Soviet spy. His quiet betrayal helped the USSR test its first atomic bomb years ahead of schedule—ending America’s monopoly on nuclear weapons and setting the stage for the Cold War. All in the name of “peace.”

"Crimes of the Centuries" is a podcast from Grab Bag Collab exploring forgotten crimes from times past that made a mark and helped change history. You can get early and ad-free episodes on the Grab Bag Patreon page.
