Raoul Gustaf Wallenberg (4 August 1912 – disappeared 17 January 1945) was a Swedish (one-sixteenth Jewish) architect, businessman, and diplomat, who is stated to have saved many Jews in German-occupied Hungary during the Holocaust using Swedish diplomatic resources.
He acted partially as an agent of the controversial War Refugee Board.
He had had various earlier associations with Jews and Zionists, including for a time living in Haifa in Palestine and later working for the Hungarian-Jewish Kálmán/Koloman Lauer.
Wallenberg was later imprisoned by the Soviet Union and subsequently disappeared. He was later reported to have died on 17 July 1947, while imprisoned at the prison at the headquarters of the Soviet secret police in Moscow.
He was only one of several diplomats in Hungary from various countries working similarly, but may been given special attention in the postwar period due to his mysterious disappearance and usefulness in anti-Communist propaganda. The controversial United States Holocaust Memorial Museum is located on the Raoul Wallenberg Place, a portion of a street renamed by an Act of Congress.
The motives behind Wallenberg's imprisonment, along with questions surrounding the circumstances of his death and his ties to United States intelligence, remain mysterious and are the subject of continued speculation.
A less politically correct explanation is that Wallenberg, who likely had extensive knowledge of Jewish deportations and migrations during the war, was killed so as to not contradict the Soviet Holocaust version.
