Hadrien Rambach writes:

He is the son of Jean Antoine Edme, ordinary court usher of the king and his wife, Marie Elizabeth Théodore, domiciled in the former rue de la Mortellerie, in the Saint-Gervais district (Paris). He was baptized in the parish of Saint-Jean-en-Grève Church on September 2, 1770. He studied law at the College of Cardinal Lemoine then worked for a while as a lawyer, before stopping for health reasons. He then became deputy curator of the , which has become the current Department of Coins, Medals and Antiques of the National Library of France. He brought together a collection of Greek and Roman coins, of which he established the catalog. His best-known works are the Description of ancient Greek and Roman medals with their degree of rarity and their estimate (1806-13, 7 vols.) And On the rarity and price of Roman medals (1815, reed. 1847). Traveling in Italy, he made many valuable numismatic discoveries which earned him being elected in 1830 to the Academy of Inscriptions and Belles Letters. He is domiciled at 14 rue des Francs-Bourgeois, in Paris.

He was made a Knight of the Legion of Honor on October 19, 1814, during the reign of King Louis XVIII. The appointment decree was signed by François Guizot, then Secretary General at the Ministry of the Interior, under Father de Montesquiou.

He is the designer of the Mionnet scale, which has 19 circles and makes it possible to precisely indicate the diameter or modulus of a part.

He is buried in the Père-Lachaise cemetery (41st division).
