Pierre Duval was born in Abbeville in 1619 and died in Paris in 1683. He was the son of Pierre Duval, a merchant and the town's consul, and Marie Sanson, the eldest sister of the famous geographer Nicolas Sanson. Duval followed his uncle to Paris and became a geographer, copying Sanson's maps and learning from him, but never reaching his level. In 1644, Duval accompanied Frédéric-Maurice, the Duc de Bouillon, to Rome. The latter was to take command of Pope Urbain VIII's armies.
Duval's first publication, Recherches curieuses des annales de France, appeared in 1640, but his first printed maps appeared in 1646. These were copies of Dutch maps he printed in collaboration with Mariette (Artois and Boulenois, Hainaut and Cambrésis, Luxembourg, Savoie). Duval worked with this merchant until 1654.
In 1650, he became the king's geographer, but he was never commissioned to publish any particular work, and it is assumed that he was given the title to give geography lessons.
Duval published Champlain's map of Canada in 1653, just before marrying Marie Desmaretz, a merchant's daughter, in 1654, and becoming an independent publisher. In fact, Duval used his wife's dowry to start investing and creating his own business, especially as he had no fortune of his own. He set up a shop on rue des Bons Enfans in Paris. Nevertheless, he continued to produce maps for other Parisian publishers such as Berey, Jollain, Langlois, Lagnet, Vouillemont and de Fer.
Duval's first atlas, "Cartes géographiques méthodiquement divisées", was published in 1654. It contained 10 maps made by him, and was completed by maps by Sanson, Briet, Boisseau, Berey Ph. De la Rue and the Dutchmen Mercator, Blaeu, Hondius and Janson. This atlas was reprinted in 1655 and 1667 under the title "Cartes de géographie les plus nouvelles et les plus fidèles". The atlas, which contained only Duval's maps, was not published until 1677. He devoted the latter part of his career to publishing maps in several sheets.
