Jean Errard or Errard de Bar-le-Duc (c. 1554 - 20 July 1610) was a mathematician and military engineer, initially in the service of the ducal court of Lorraine and then (after converting from Protestantism to Catholicism) of Henry IV of France. He introduced Italian bastions to France and was a forerunner of Vauban as well as uncle to the painter Charles Errard the Elder. He has been called the "father of French fortification".
