Alexander of Villedieu was a French writer, teacher and poet, who wrote text books on Latin grammar and arithmetic, everything in verse. He was born around 1175 in Villedieu-les-Poêles in Normandy, studied in Paris, and later taught at Dol in Brittany. His greatest fame stems from his versified Latin grammar book, the Doctrinale Puerorum. He died in 1240, or perhaps in 1250. He was a Franciscan and a Master of the University of Paris.
