Nicolas Maire (fl. 1803 - 1840) was a French engraver active in Paris in the late 18th and early 19th centuries. Little is known of his early years during the chaotic days of the French Revolution, but some argue that he was a military engineer under Louis Brion de la Tour (1743 - 1803). During the First Empire, under Napoleon Bonaparte, he established himself as a commercial cartographer, leverage the expanding empire's growing access to cartographic data. He successfully negotiated the political upheavals after the Battle of Waterloo, acquiring the prestigious post of Ingenieur et Geographe du Roi during the Bourbon Restoration of Louis XVIII (1755 - 1824). Maire was an early pioneer of data visualization through maps - and most of his maps are correspondingly data rich and large. In 1821, he published an Atlas Administratif de Pairs which employed a unique template and coding system to visualize urbanization data. He also issued an impressive and rare mineralogical map of Italy, as well as other significant thematic pieces.
