Altfrid
Altfrid bishop of Hildesheim from 851, to 874, is said to have been a monk at Corvey before his elevation to the bishopric. The ordinations performed by his predecessor, bishop Ebbo, who died March 20, 851, he declared null and void, because he regarded the translation of Ebbo from Rheims to Hildesheim as in conflict with the laws of the Church. He took an active part in the affairs of Church. and State, and was present at the synods held at Mayence in 852 and 857, at Worms in 868, and at Cologne in 873. He founded many monasteries, and through, his efforts the cathedral at Hildesheim was built, which he dedicated in 872. He died Aug. 15, 875.
