A landmark map in the history of cartography.
Jean-Claude Dezauche (fl. 1780-1838) was a French map publisher. Initially, his work focused on engraving music, but he later turned primarily to cartography. His is best known for editing and reissuing the maps of Guilluame De L’Isle and Philippe Buache, two of the most skilled mapmakers of the eighteenth century. He acquired the plates of these two men’s work in 1780 from Buache’s heir, Jean-Nicolas Buache. Dezauche's business received a further boon when he received a privilege to sell the charts of the Dépôt de la Marine. His business was carried on by his son, Jean-Andre Dezauche.
