Thierry of Chartres
Thierry of Chartres ("Theodoricus Chartrensis") or Theodoric the Breton ("Theodericus Brito") (died before 1155, probably 1150) was a twelfth-century philosopher working at Chartres and Paris, France.
The cathedral school at Chartres promoted scholarship before the first university was founded in France.
Thierry was a major figure in twelfth-century philosophy and learning, and, like many twelfth-century scholars, is notable for his embrace of Plato's "Timaeus" and his application of philosophy to theological issues.
Some modern scholars believed Thierry to have been a brother of Bernard of Chartres who had founded the school of Chartres, but later research has shown that this is unlikely.
Thierry became chancellor of Chartres after his predecessor, Gilbert of Poitiers, returned to his native city in 1141.
John of Salisbury, Herman of Carinthia, and Clarembald of Arras were among Thierry's students.
