  ## Biography
  
  Born in a family of Burgundian bourgeoisie, Guérard studied in Dijon from 1807 to 1814, then moved to Paris where he was first a bank employee.
  
  In 1818, he obtained a supernumerary place at the manuscript department of the Bibliothèque royale and decided to improve his training by following the course of the École royale des chartes established in 1821.
  
  Became permanent employee of the Royal Library, he devoted himself to historical research, getting a mention from the Académie française for his Discours sur la vie et les ouvrages du président Jacques-Auguste de Thou and collaborated to the L'Art de vérifier les dates. But he is mostly known for his Essai sur les divisions territoriales de la Gaule sous les rois des Francs, crowned by the Académie des Inscriptions et Belles-Lettres (1830) and printed at government expense in 1832.
