Guillaume Delisle (1675-1726)
Leading French cartographer of the C18th who was reknown for the accuracy of his maps.
He studied under Jean Cassini and from an early age showed his talent. At the age of 27 Delisle was admitted to the Academie Royale des Sciences and by 1718 he had been made the Royal Geographer. His maps reflect his scientific approach to map making by including the most up to date cartographic information as well as the use of new astronomical information. Where he was unable to verify information conclusively, he would note the fact on his maps.
Pierre Mortier (1661-1711)
Pierre Mortier was one of the most important map publishers of his time. Born in Leiden, Holland, but of French Huguenot decent, he managed to gain the rights to republish many important French maps and atlases in Amsterdam. This occurred at the very time that the French assumed the global lead in cartography publishing. The present map is from Mortier’s edition of the Neptune François, considered to be the finest sea atlas of its time. It was first issued in Paris by Alexis-Hubert Jaillot in 1693. Following his death, Pierre’s business was taken up by his son, Conelius Mortier, who in 1721 formed a lucrative partnership with Johannes Covens. The resulting firm, Coven & Mortier remained in business until 1866.
