Swedish diplomat Raoul Wallenberg, who saved the lives of Jews in Budapest, Hungary and disappeared after being taken away by Soviet soldiers on January 17, 1945. Wallenberg was tireless in his efforts to save Jews from deportation. He pursued convoys of prisoners and confronted Hungarian and German guards to secure the release of Jews whom he claimed were under Swedish protection. He issued thousands of "protective passes," put some 15,000 Jews into dozens of "safe houses," and helped foil a plot to blow up the remaining Jews in the Budapest ghetto on the eve of its liberation. While being accompanied by Soviet soldiers in January 1945 after they liberated Hungary, Wallenberg was heard to say, “I do not know whether I am a guest of the Soviets or their prisoner.” Afterwards, Wallenberg disappeared without a trace.
