Fulbert of Chartres was the Bishop of Chartres from 1006 to 1028 and a teacher at the Cathedral school there. Fulbert was a pupil of Gerbert of Aurillac, who would later become Pope Sylvester II. He was responsible for the advancement of the Nativity of the Virgin's feast day on September 8 and for one of the many reconstructions of the Chartres Cathedral. Most of the available information about him is found in the letters he wrote from 1004–1028 to both secular and religious figures of the day.
