Guillaume Delisle

Guillaume Delisle, also spelled Guillaume de l'Isle, (; 28 February 1675, Paris – 25 January 1726, Paris) was a French cartographer known for his popular and accurate maps of Europe and the newly explored Americas. Childhood and education Delisle was the son of Marie Malaine and Claude Delisle (1644–1720). His mother died after childbirth and his father married again, to Charlotte Millet de la Croyère. Delisle and his second wife had as many as 12 children, but many of them died at a young age. Although the senior Delisle had studied law, he also taught history and geography. He had an excellent reputation in Paris’ intellectual circles, and served as a tutor to lords. Among them was the duke Philippe d’Orléans, who later became regent for the crown of France, and collaborated with Nicolas Sanson, a well-known cartographer. Guillaume and two of his half-brothers, Joseph Nicolas and Louis, ended up pursuing similar careers in science. While his father has to be given credit for educating Guillaume, the boy showed early signs of being an exceptional talent. He soon contributed to the family workshop, by drawing maps for his father's historical works. Some have questioned the authorship of these first maps, saying that Delisle only copied what his father had done before him. In order to perfect his skills, Guillaume Delisle became the student of the astronomer Jean-Dominique Cassini. Early on he produced high-quality maps, the first being his Carte de la Nouvelle-France et des Pays Voisins in 1696. Career
