One of the most important French geographers and mapmakers of the second half of the eighteenth century. Successor to Nicolas Sanson (1600-1667), Robert de Vaugondy (1686-1766), and Rigobert Bonne (1727-1794), whose atlases he reprinted. Also taught geography. In addition to maps and globes, his works include a treatise on the use of the sphere and celestial and terrestrial globes. In the treatise, he illustrates both the Ptolemaic and Copernican systems, as well as listing all the ancient and modern constellations. His son Félix (18th C. - 1st half 19th C.) continued his work.
