"Jacques Roettiers (20 August 1707 – 17 May 1784) was a noted engraver in England and France, and one of the most celebrated Parisian goldsmiths and silversmiths of his day.
Roettiers was born in Saint-Germain-en-Laye, near Paris, to Norbert Roettiers (1665–1727) and his wife Winifred Clarke, niece of John Churchill, Duke of Marlborough. As a Roettiers, he was born into a distinguished family of medallists, engravers, and goldsmiths. Roettiers studied drawing and sculpture at the Académie Royale de Peinture et de Sculpture, winning a prize to be pensionnaire du Roi at the French Academy in Rome. Instead he remained in Paris to learn medal-engraving and in 1732 moved to London. There he was appointed Engraver at the Royal Mint." - (Wikipedia (en) 03.01.2021)
