Before the United States joined World War II, the FBI uncovered a ring of Nazi spies in New York City, and President Franklin Roosevelt declared J. Edgar Hoover as America’s spymaster. As war began, a naturalized German-American was recruited by Nazis to convey messages to Germany. This man, William G. Sebold, approached the FBI and became the first double agent in the Bureau’s history, and the investigation led to the arrest of 33 enemy agents.
