Bengt Olander, a Swede from Gothenburg, had an early education about Raoul Wallenberg, Sweden's hero from the Holocaust.
At 7, visiting his grandmother's apartment every day, Olander met a Hungarian woman, one of several refugees from Hungary his grandmother housed after the 1956 Revolution. He noticed something unusual about the woman.
"She always looked so sad," Olander recalled.
He asked why. She told him she was a Jew who had almost died during the Holocaust.
