Gilles Robert de Vaugondy*; 1688-1766.
Didier Robert de Vaugondy, son; c1723-1786.
Charles François Delamarche, successor; 1740-1817.

Vaugondy, related to the Sanson family, inherited a wealth of cartographic materials in 1730 at Pierre Moulard Sanson's passing away. He had also acquired most of the plates and maps of Hubert Alexis Jaillot upon his death in 1712.
With ample revisions, corrections and additions, this was the basis for his major work: "Atlas Universel" first printed in 1757, and later reissued in 1783 and 1793.
Worth mentioning is also the "Atlas portatif" in 1748-1749.
His son produced in 1761 the famous "Part de l'Amérique septentrionale", and later a "Nouvel atlas portatif".
Delamarche, corrected and revised as necessary to continue publish quite a few of these works (e.g.: "Nouvel atlas portatif" of 1806); often giving prominent credit to his source (which may be misleading in some cases).

* Gilles is often marking his maps: Le Sieur, or: Monsieur Robert.

Gallia antiqua in provincias et populos divisa,...

This large map (21 ½" X 19") of the roman time Gauls (Gallia,) probably printed first as an isolated item in 1750.
The present item has been incorporated in the 1757 first edition of "Atlas Universel".
The overall delineation is extremely accurate, and it became soon the seminal work inspiring all later cartography* of France.
The research on the different colonial roman province organization is very scholarly (17 provinces: Germania (2), Belgica (2), Lugdunensis (4), Aquitania (2), Narbonensis (2), Novem Populania, Viennensis, Maxima Sequanorum, Alpes (2)). Notice how the Gauls territory encompassed not only France, but also significant portions of Belgium, Luxemburg, Holland, Germany, Switzerland and Italy. No text on verso.

* "Models" for mapping France evolved: The original 1480 Berlinghieri gave way to the 1530'ies "Gastadi/Munster" model, which was replaced in 1570 by the "Jolivet/Ortelius" design, supplanted in the 1650'ies by the Sanson delineation, in turn replaced in 1681 by the "La Hire-Cassini-Picard" standard, and finally giving way to the 1750 Vaugondy model.
