You read about St. Norbert here on the New Advent website. An excerpt:
Born at Kanten on the left bank of the Rhine, near Wesel, c. 1080; died at Magdeburg, 6 June, 1134. His father, Heribert, Count of Gennep, was related to the imperial house of Germany, and his house of Lorraine. A stately bearing, a penetrating intellect, a tender, earnest heart, marked the future apostle. Ordained subdeacon, Norbert was appointed to a canonry at Kanten. Soon after he was summoned to the Court of Frederick, Prince-Bishop of Cologne, and later to that of Henry V, Emperor of Germany, whose almoner he became. The Bishopric of Cambray was offered to him, but refused. Norbert allowed himself to be so carried away by pleasure that nothing short of a miracle of grace could make him lead the life of an earnest cleric. One day, while riding to Vreden, a village near Kanten, he was overtaken by a storm. A thunderbolt fell at his horse's feet; the frightened animal threw its rider, and for nearly an hour he lay like one dead. Thus humbled, Norbert became a sincere penitent. Renouncing his appointment at Court, he retired to Kanten to lead a life of penance.
