Cartographer: The Amsterdam publishing firm of Covens and Mortier (1721 – c. 1862) was the successor to the extensive publishing empire build by Frenchman Pierre Mortier (1661 – 1711). Upon Mortier’s death in 1711 his firm was taken over by his son, Cornelius Mortier (1699 – 1783). Cornelius married the sister of Johannes Covens (1697 – 1774) in 1821 and, partnering with his brother in law, established the Covens and Mortier firm. Under the Covens and Mortier imprint, Cornelius and Pierre republished the works of the great 17th and early 18th century cartographers De L’Isle, Allard, Jansson, De Wit, and Ottens among others. The quickly became one of the largest and most prolific Dutch publishing concerns of the 18th century. The firm and its successors published thousands of maps over a 120 year period from 1721 to the mid 1800s. During their long lifespan the Covens and Mortier firm published as Covens and Mortier (1721-1778), J. Covens and Son (1778 – 94) and Mortier, Covens and Son (1794 – c. 1862). Cartographer: The De L’Isle family (fl. c. 1700 - c. 1760) was one of the most important cartographic dynasties working in early 18th century France. Claude De L’Isle (1644 -1720), the family patriarch was a minor geographer and historian based in Paris. His four sons, Guillaume (1675- 1726), Simon Claude (1675 - 1726), Joseph Nicholas (1688 – 1768) and Louis (1720 – 1745) each made an important contribution to cartography. Without a doubt Guillaume was the most remarkable member of the family. It is said that Guillaume’s skill as a cartographer was so prodigious that he drew his first map at the age of nine. He was tutored by J. D. Cassini in astronomy, science, mathematics and cartography. By applying these diverse disciplines to the vast stores of information provided by navigators, Guillaume created the technique that came to be known as “scientific cartography”. This revolutionary approach transformed the field of cartography and created a more accurate picture of the world. Among Guillaume’s many firsts are the first naming of Texas, the first correct map of the Mississippi, the discarding of the “California as an Island fallacy”, and the first identification of the first correct longitudes of America. Guillaume was elected to the Academie Royale des Sciences at 27. Later, in 1718, he was also appointed “Premier Geographe du Roi”, an office created especially for him. De L’Isle personally financed the publication of most of his maps, hoping to make heavy royalties on their sales. Unfortunately he met an untimely death in 1728, leaving considerable debt and an impoverished child and widow. De L’Isle’s publishing firm was taken over by his assistant, Phillipe Buache who became, posthumously, his son in law. The other De L’Isle brothers, Joseph Nicholas and Louis De L’Isle, were employed in the Service of Peter the Great of Russia as astronomers and surveyors. They are responsible for cataloguing...
