(Otho, Otto or Odo of Lagery), 1088-1099, born of a knightly family, at Châtillon-sur-Marne in the province of Champagne, about 1042; died 29 July, 1099. Under St. Bruno (afterwards founder of the Carthusians) Otho studied at Reims, where he later became canon and archdeacon. About 1070 he retired to Cluny and was professed there under the great abbot St. Hugh. After holding the office of prior he was sent by St. Hugh to Rome as one of the monks asked for by Gregory VII, and he was of great assistance to Gregory in the difficult task of reforming the Church. In 1078 he became Cardinal Bishop of Ostia and Gregory’s chief adviser and helper.
