Coitier was born at Poligny, Franche-Comté. His name is spelled in several ways, most often Coictier (the spelling used by Victor Hugo in his novel The Hunchback of Notre-Dame), but also Coittier, Cotier, Coytier or Coctier. An analysis of his signatures by Achille Chereau has allowed Coitier to become the standard spelling - this was the name cited most often in medical annals.^[1] He died in Paris.
