925-965. Archbishop of Cologne. He was educated at the cathedral school in Utrecht, then at the court of his brother Otto I. Abbot of the monasteries of Lorsch near Worms and of Carvei on the Weser from 941, he became arch-chaplain to Otto in 951. As archbishop from 953 he contributed greatly to every department of Otto's reign. With great personal sanctity and deep concern for clerical and lay education, he was a generous benefactor of churches and monasteries, having established three foundations in Cologne. An exemplary prince- bishop, he demonstrated the successful union of church and state. He participated in the Synod of Verdun (947) and improved relations between France and Germany. He was also a patron of learning. His disciple, Ruotger, wrote his biography shortly after Bruno's death.
