Josephine Baker: International Spy

When World War II rocked her adopted France, Baker didn't simply move to a more peaceful country. Instead, she stuck around and did her part for the war effort. Since she had initially publicly supported Mussolini's invasion of Ethiopia, the Axis powers mistakenly thought she was "one of them," and Baker took full advantage of this misconception.

In fact, her fame made her the perfect spy. When Baker would travel Europe while touring, she obviously had to carry large quantities of sheet music with her. What customs officials never realized, though, was that a lot of this music actually had secret messages written on it in invisible ink. Fawning immigration officials never thought to take too close a look at the diva's luggage, so she could sneak all sorts of things in and out of countries. On some occasions, Baker would smuggle secret photos of German military installations out of enemy territory by pinning them to her underwear.

This invaluable intelligence work eventually helped Baker rise to the rank of lieutenant in the Free French Air Force, and when the war was over she received both the Croix de Guerre (a first for an American woman) and the Medal of the Resistance in 1946.
