Hitler's Personal Spy: Fritz Julius Kuhn in America

Before WWII reached America, Nazi agent Fritz Julius Kuhn led the German American Bund — a pro-Nazi organization of 25,000 members in the United States. He was so bold that he held a pro-Nazi rally at Madison Square Garden in 1939 with 20,000 attendees while a 75-foot-tall portrait of George Washington hung behind him. Kuhn was eventually brought down not by the FBI but for embezzling money from his own organization. He served time in an American prison and was then deported to Germany after the war, where he died penniless in Munich.
