- Raoul Wallenberg (Wikipedia)
Raoul Gustaf Wallenberg (4 August 1912 – disappeared 17 January 1945) was a Swedish architect, businessman, diplomat, and humanitarian. He saved thousands of Jews in German-occupied Hungary during the Holocaust from German Nazis and Hungarian fascists during the later stages of World War II. While serving as Sweden’s special envoy in Budapest between July and December 1944, Wallenberg issued protective passports and sheltered Jews in buildings he declared as Swedish territory.
