DUVIVIER, Jean: Jean Duvivier (1687-1761) was born in Liege and went to Paris in 1710, where he worked for most of his remaining life. In 1719, Louis XV selected him to succeed Mauger as the official medallist to the king. The work of Jean Duvivier was prodigious, having engraved over four hundred dies. He was the most important medallist of Louis XV's reign, much as Warin, his predecessor, was that of Louis XIV's. Although Duvivier never attained the high degree of art of Warin, he remains, nevertheless, one of the greatest medallists of the eighteenth century.

DUVIVIER, Pierre Simon Benjamin: Benjamin Duvivier (1728-1819) was the son on Jean Duvivier. It is said that Jean, fearing to be surpassed by his son, not only did not teach Benjamin medallic art, but actually drove him from his home when the son was caught copying a medal. Benjamin was taken under the protection of his brother-in-law, and on the death of his father, he devoted himself to the king's service, becoming one of the favorite artists of the Court of Louis XVI. In 1774 Duvivier was given the office of Engraver at the Mint, formerly held by Joseph Charles Roettiers.
