Anno or Hanno
Anno or Hanno (St.), archbishop of Cologne in the 11th century. Belonging to the Suabian family of Sonneberg, he was at first devoted to a miilitary life; but, after a short career of arms, he entered the church. The emperor Henry III, the B'ack, appointed him to the see of Cologne upon the death of archbishop Hermann in 1055. He applied himself with diligence to his duties, both temporal and spiritual. He reformed many of the monasteries of his diocese, aid built five or six others, among the latter the abbey of Siegberg, After the death of Henry III the empress made him regent. His zeal for the church outran his discretion, especially in the excessive energy with which he seconded the measures of Gregory VII (q.v.). The emperor Henry IV, though his pupil, was so dissatisfied with his conduct that he drove him from his see. He died December 4th, 1075, on which day he is commemorated. — Hoefer, Nouv.
