Guillaume de L'Isle (1675-1726) was a cartographer and the Premier Geographer to the King in France beginning in 1718. His family played a significant part in the world of French cartography in the eighteenth century. At age 9, he drew his first map and at age 27 he became a member of the Académie Royale des Sciences. He studied under Jacques Cassini, acquiring knowledge in both mathematics and astronomy. Due to his academic background and his "critical approach to the maps of his predecessors," he became known as the first "scientific cartographer" (Moreland and Bannister, 132). Among his works are "Globe, map of the world and the four continents" (1700), "Atlas de Géographie" (1700-12), "Mississippi" (1701), "Carte du Mexique et de la Floride…" (c.a. 1703), "Carte de la Louisiane et du Mississippi" (1718) and posthumously, "Atlas Noveau…" (1730 and later). Following his death, his widow took up the business with a partner, Philippe Buache (Moreland and Bannister, 131-2; Tooley, "Dictionary," 395). Jean Baptiste Delahaye was an engraver. He engraved for de L'Isle in 1724 (Tooley, "Dictionary" 155). This particular map was first published in 1724 and later republished in 1745 under Buache. Wagner notes that this map in combination with his "Hémisphere Oriental" was the last map De L'Isle made of the world (Wagner, 329, entry 527). Source(s): Moreland, Carl and David Bannister.
