Guillaume Dauberive
Guillaume D'auberive a French abbot and theologian, lived in the 12th century. In 1165 and 1180 he was at the head of the abbey of Auberive, which was of the order of Cistercians, in the diocese of Langres. He composed various books, which have remained unedited, however; there are cited among them four letters on the last judgment, and a treatise upon numbers, which reveals a profound knowledge of arithmetic.
