Johannes I Pfefferhard

Johannes I Pfefferhard (born before 1300, died 23 May 1331), a cleric from a wealthy Konstanz patrician family, served as bishop of Chur from 1325 until his death. He studied at Bologna and held church posts at Steffisburg, Chur, Konstanz and Würzburg.

He sided with the pope against Emperor Louis IV. Consecrated at Avignon in 1330, he was seized on his way home by the barons of Grünenberg and held in a castle called Tüfelsruggen; he died in captivity and was buried at Binzen.
