Whatever happened to Raoul Wallenberg?

"Raoul Wallenberg was a minor official of a neutral country, with an unimposing appearance and gentle manner. Recruited and financed by the United States, he was sent into Hungary to save Jews. He bullied, bluffed and bribed powerful Nazis to prevent the deportation of 20,000 Hungarian Jews to concentration camps and averted the massacre of 70,000 more people in ghetto by threatening to have the Nazi commander hanged as a war criminal. Then, on Jan. 17, 1945, days after the Soviets moved into Budapest, the 32-year-old Wallenberg and his Hungarian driver, Vilmos Langfelder, drove off under a Russian security escort and vanished forever."
