German preacher and spiritual writer. Probably a native of Augsburg, he entered the Franciscan Order at Regensburg; later he was transferred to the newly founded house at Augsburg. His main Latin works are a three-part treatise De Compositione, often ascribed to St Bernard and to St Bonaventure, and two letters. The attribution of others is disputed. He is generally regarded as the first author to publish spiritual writings in German; some of these are based on Latin works, some are independent compositions. His teaching is eminently practical.
