Maurus Xaverius Herbst was an 18th-century German Benedictine monk and theologian. Born in Pleinfeld in 1701, he later served as the abbot of the Benedictine Abbey of Plankstetten, a position he assumed in 1742. During his childhood, he was briefly taken by imperial soldiers during the Spanish War of Succession before returning to his family. He passed away in Abenberg in 1757, following an attempt at an exorcism. He is recognized as a blessed figure within the Catholic tradition.
