Now an international symbol of twentieth-century humanitarianism, Raoul Wallenberg, the Swedish diplomat, issued countless "false" visas and other documents which were virtual life certificates that saved approximately 100,000 Jews from Nazis in wartime Hungary. Then in 1945, as the war drew to a close, he disappeared after being taken into custody by Soviet military police. Today his fate is still unknown.The expanded version of this authoritative biography of Wallenberg discusses previously sealed prison records and archives; reports of recent sightings of Wallenberg; the Wallenberg family's historic multi-million-dollar lawsuit against the former Soviet Union; and the worldwide activities in honor of this great man who could not be a bystander.
