On Monday morning, when the Simon Wiesenthal Center observes Yom HaShoah, commemorating the victims of the Holocaust, a place of honor will be reserved for the daughter of the late Khaled Abdelwahab. Abdelwahab is the first Arab to be nominated for official recognition by Yad Vashem as a Righteous Among the Nations, and his story adds a new dimension to the 6 million stories of horror — and occasionally nobility — rising from the ashes of the Holocaust. His acts also shed light on the little-known fates of Jews in the Arab countries of North Africa during World War II.
