Note 31 — I DESCENT AND PARENTAGE; CHILDHOOD AND GIRLHOOD (LEYDEN, THE HAGUE, AND RHEENEN, 1630-1650)
Reading edition
The honour of having discovered the art of engraving in mezzotint, frequently claimed for Prince Rupert, seems due to a Hessian officer named Ludwig von Siegen, who, meeting the Prince at Brussels about 1654, taught him the new process. See Cyril Davenport, Mezzotints (‘The Connoisseur’s Library,’) pp. 52-65.
