The rare last edition of the De L'Isle-Buache Map of the America. The first edition of this map appeared in 1722. It went through a total of 19 incarnations, tracking most of the great cartographic evolutions of the 110 year life of the map. From the first De L'Isle edtion, the map evolved through rare Russian variants, the Fricx Belgian edition, the Covens & Mortier and Buache editions which introduced the Bay of the West, to the early Dezauche editions, which tracked the evolving knowledge of the NW Coast of America and finally to this rare late Dezauche edition (Tooley #19), which shows a 54-40 or fight Oregon border and an inset with the most recent information concerning Russian America.
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.
