Chartier, Guillaume, a French prelate, was born at Bayeux about 1400. Like his brother Alain, and probably upon the recommendation of the latter, he became a scholar of the University of Paris. After having acquired the degree of licentiate of civil and common law, he sought reputation as a poet. In 1432 he was appointed professor of canonical jurisprudence in the newly erected University of Poitiers, by Charles VII. Soon afterwards he became pastor of St. Lambert, near Saumur, and canon of Tournay. Next he was called as canon of the cathedral in 1436, counsellor of the Parliament of-Paris, chancellor of Notre Dame, and finally bishop of that see, Sept. 4, 1447. He interceded with the archbishop of Rheims to settle the quarrel between the mendicants and the university. In 1455 he was one of the papal commissioners to effect the rehabilitation of Joan of Arc. In 1459 he took part in 'the Convention of Mantua, which was called by Pius II against the Turks. He was at first in favor with Louis XI, but afterwards fell under the displeasure of that prince. He died in Paris, May 1, 1472. See Hoefer, Nouv. Biog. Generale, s.v.
