Raoul Gustaf Wallenberg 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 which he declared as Swedish territory.

Wallenberg was born in 1912 in Lidingö Municipality, near Stockholm, where his maternal grandparents, Per Johan Wising and his wife Sophie Wising (née Benedicks), had built a summer house in 1882. His paternal grandfather, Gustaf Wallenberg, was a diplomat and envoy to Tokyo, Istanbul, and Sofia.
