Noor Inayat Khan
Nicknamed The Spy Princess, Noor was a descendant of Indian royalty raised in Britain and France. The elite Special Operations Executive recruited her in 1942 to work as a radio operator because of her bilingual abilities. Serving as a spy during World War II, she faced imprisonment, torture, and was eventually killed at Dachau concentration camp. Considered a British heroin of World War II, a statue of her is located in Gordon Square Gardens, London, to commemorate her bravery and service.
