His role as abbot is mentioned for the first time in a document from the 12 June 947, in which Otto I granted him the right of coinage in Rorschach.
He was somewhat successful economically, as attested by eight sales or donation of goods to the Abbey of Saint Gall between 948 and 957.
He died before the defeat of Liudolf, so when Cradolf returned he found the abbey under the rule of the monk Viktor.
Bishop Ulrich of Augsburg reconciled the convent with the abbot, who ultimately destroyed the monks' trust by sending armed men after Viktor to blind him as he was fleeing to his relatives.
[1] During the time in which he resided in Herisau, he let Dean Ekkehard I run the abbey on his behalf, wishing him to become next abbot after he died.
