Altmann of Passau
German bishop
Feast: 8 August (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Altmann was born at Paderborn early in the eleventh century, headed its school, was chaplain at the court of Henry III, and became Bishop of Passau and papal legate, a friend of Pope Gregory VII.
He was famous for his care of the poor, his reform of relaxed monasteries and building of new ones, and the splendour of divine worship, and for enforcing Gregory's decree on clerical celibacy, which brought him strong opposition. He died in 1091.
The miracles

Why that counted as sanctity
