"Ambroise Tardieu (2 March 1788 in Paris – 17 January 1841 in Paris) was an eminent French cartographer and engraver, and is celebrated for his version ...
of John Arrowsmith´s 1806 map of the United States. Tardieu´s son, Auguste Ambroise Tardieu (1818–1879), was also an artist and a famous forensic medical scholar, who supplied the illustrations for Dr. Pierre François Olive Rayer´s three-volume Traité des maladies des reins (1839–41), a treatise on diseases of the kidneys. Neither should be confused with Jean Baptiste Pierre Tardieu, an unrelated French cartographer and engraver active in the early 19th century." - (en.wikipedia.org 06.11.2019)
