(called Sans Pitie), bishop of Liege, lived at the commencement of the 15th century. He filled the country with troubles and scandals. The people of Liege revolted against him, and opposed to him Thierry of Harnes. Jean vanquished them in the bloody battle of Othee, and deprived them of their liberty arid privileges. He allied himself with the count of Hainaut and the duke of Burgundy against France. In 1418 he obtained the subdeaconrv, left the bishopric of Liege, and married the widow of Anthony, duke of Burgundy. See Hoefer, Nouv. Biog. Generale, s.v.
