Dictionary of National Biography, 1885-1900/William de Leicester
WILLIAM de Leicester, or WILLIAM du Mont (d. 1213), theologian, studied at Oxford, and afterwards proceeded to Paris, where he taught on the Mount St. Geneviève between 1170 and 1180; he seems to have taken his name of du Mont from this fact. He afterwards became chancellor of Lincoln, an office which he held in 1192 and 1200 (Le Neve, Fasti, ii. 91). Here he continued his lessons with great success, numbering among his pupils Giraldus Cambrensis, whom he had previously met in Paris (Gir. Cambs. De Rebus a se Gestis, iii. 3). He died soon after Easter 1213.
