"Werner, Adam Rudolph (Germ.). Son of Peter Paul Werner, born at Nuremberg, Mint-engraver at Stuttgart from 1742 till his death in 1784; was also Court Medaillist of the Duke of Württemberg.
Among German artists, he was one of the latest, says Erman, who practiced the art of casting metals, and his productions are by no means wanting in artistic merit.
He signed: A. R W.; A. R. WERNER; A. R. WERNER F.; A. R. WERNER. FEC. etc." - Forrer, Leonard, "Biographical Dictionary of medaillists", Band 6, London 1916, S. 448
