Jacquard’s surname was not technically “Jacquard”; it was Charles. In his grandfather’s generation, several branches of the Charles family lived in Lyon’s Couzon-au-Mont d’Or suburb (on Lyon’s north side, along the Saône River). To distinguish the various branches, they were given nicknames; Joseph’s branch was dubbed the “Jacquard” Charles. Thus, Joseph’s grandfather was Barthélemy Charles dit [called] Jacquard.
