Longchamp, William de, a low-born Norman favourite of Richard I., made by him bishop of Ely; became Justiciar of England 1190, and Papal Legate 1191; clever, energetic, just, and faithful, he yet incurred dislike by his ambition and arrogance, and was banished to Normandy; his energy in gathering the money for Richard's ransom restored him to favour, and he became Chancellor; (d. 1197).
