Geographer to the King of France, like his father, Gilles-Robert (Paris, 1688-1766), he continued and completed his father’s work. He dedicated himself from an early age to building terrestrial and celestial globes, presenting his first version to the King of France in 1751. He wrote Institutions Géographiques (1766), contributed to Diderot’s Encyclopédie and Buffon’s Histoire Naturelle, and was appointed Géographe Ordinaire du Roy. The Palatine Library in Caserta displays a pair of his globes (one terrestrial, one celestial) and boasts a major collection of maps gathered by the Robert de Vaugondys (father and son).
