Born to the Swabian nobility, when Hatto came of age he gave all his property to the Benedictine abbey at Ottobeuren, and became a monk there. He left the abbey to live as a hermit on his old lands; his abbot saw that being a hermit was merely an excuse to live on his old property, and promptly summoned back to community life.
