John the Deaf [I]

Also known as Jean le Surdus and John the Physician of Chartres; was teacher of Droco and of Roscellinus during the "Age of Alcuin" in the "Carolignian Renaissance". Considered by scholars to be the founder of nominalism, a branch of philosophy. It is not certain that he actually was deaf; "Le Surdus" ("The Deaf") may have been a family name rather than an actual description.
