Ingrad Carlberg, author of “Raoul Wallenberg: The Man Who Saved Thousands of Hungarian Jews from the Holocaust,” joined Glenn Beck in the studio to share the untold story of a hero during the Holocaust who saved thousands of Hungarian Jews during World War II, then disappeared, never to be seen or heard from again.

In 1944, the War Refugee Board, a group established by the United States to rescue European Jews and other Nazi victims, appointed 31-year-old Raoul Wallenberg to be special envoy to Budapest, Hungary. A business man from an affluent Swedish family, Wallenberg seemed the ideal candidate as he was familiar with Budapest, spoke Hungarian and German, and was sympathetic to the plight of Jews.

Upon arriving in Budapest, Wallenberg opened an embassy office and used protective passports or employment at the embassy’s faculty to grant diplomatic immunity to thousands of Jews (some say as many as 100,000) who faced genocide during Adolf Hitler’s Nazi regime. But as the war drew to a close, he was arrested as a spy and disappeared into the Soviet prison system. Wallenberg was never seen again.

In the clip above, Ingrid shares her insight into Wallenberg’s heroic life and the mystery behind his disappearance and death.
