Bishop of Breslau, b. at Rüdesheim on the Rhine, about 1402; d. at Breslau in Jan., 1482. From 1422 to 1426 he studied at the University of Heidelberg from which he graduated as master. He then proceeded to Italy, graduated as doctor in ecclesiastical law and became auditor of the Rota. Numerous benefices were conferred upon him at an early date, particularly in the dioceses of Mainz and Worms. From 1438 onward he represented the cathedral chapter of the latter city at the schismatic Council of Basle, where he formed a friendship with Enea Silvio de' Piccolomini, subsequently Pope Pius II. The latter, his successor Paul II, and the Emperor Frederick III entrusted Rudolf with important missions and difficult negotiations. Pius II named him in 1463 Bishop of Lavant in Tyrol. The See of Breslau was conferred on him in 1468, at a time when the inhabitants were spiritedly resisting their ruler, George Podiebrad, King of Bohemia. The latter had been deposed and excommunicated, but maintained his position as ruler. The war which resulted was protracted beyond Podiebrad's lifetime and terminated, with Rudolf's co-operation, in the Peace at Olmütz in 1479. Now intent more exclusively upon the spiritual welfare of his diocese, the bishop sought to heal the wounds of the war, endeavoured to imbue the diocesan secular and regular clergy with a sound ecclesiastical spirit, and insisted upon the importance of their proper theological training. The acts of the synods held in 1473 and 1475 bear witness to the zeal and energy of the skilful prelate.
