Raoul Wallenberg
A Swedish diplomat in Budapest at the end of World War II, Roaul Wallenberg was responsible for saving upwards of 100,000 Jewish lives. He set up safe houses and issued protective passports to Hungarian-Jews at the time. However, outside of Budapest, he was taken by the Soviets and never heard from again. Years later, Soviets admitted to taking Wallenberg but claimed he died of a heart attack. His family and several authorities in Sweden dispute these claims and believed he may have lived much longer under their custody. Their reasoning was that the Soviets thought Wallenberg was a spy for the West and wanted him for information.
