Nicolas Tardieu (c. 1650- c. 1700) was a French geographer and the father of the prolific Tardiu family of engravers. He was given the title 'géographe ordinaire du roi' and married Marie Hénin, the daughter of Frédéric Horthemels, who was also a distinguished engraver. Nicolas-Henry and Marie had four sons: Charles, Claude, Jean, and Nicolas-Henry, each of whom was an artist and whose descendants also became artists.
