Spies are usually defined by what they prevented. But one spy is credited with saving more lives than almost any other in history. His name was Oskar Schindler? No. This man was a German businessman named Fritz Kolbe.

During World War II, Fritz Kolbe worked as a mid-level diplomat in the German Foreign Office. He wasn’t a high-ranking Nazi, but he had access to a steady stream of cables and secret messages. Kolbe was horrified by the Nazis. In 1943, he decided to act. He walked out of the office with a pile of top-secret documents stuffed in his pants and took a train to Switzerland.

He walked into the American Legation in Bern and offered to spy. The Americans were suspicious. They thought he was a plant. But they tested his information. He provided details about German spies in the US, the location of V-2 rocket factories, and plans for German defenses in France. Every piece was accurate. Over the war, Kolbe smuggled out over 1,600 documents. His intelligence was so good it was code-named “Boston” and sent directly to President Roosevelt.

Why was he effective? He wasn’t caught. He kept his day job. He didn’t work for money (the US had to force him to take payment). He did it purely out of hatred for the regime. Historians say his intelligence shortened the war by months, saved thousands of lives, and provided crucial intel for the D-Day landings. After the war, he was largely forgotten because the Allies didn’t want to admit a German had done so much to help them. He is arguably the most effective spy in history.
