Hidulf was a 7th-century Benedictine abbot and a saint recognized by both the Catholic and Orthodox churches. Born around 601, likely in Regensburg, he was a member of a noble family and studied there before moving to the Abbey of Saint Maximin in Trier. He is most notably remembered as the founder of Moyenmoutier Abbey, where he served as the first abbot. While some traditions identify him as the bishop of Trier, others suggest he may have served as a chorepiscopus, an auxiliary bishop assisting in missionary regions.
