Charles Turner (1773-1857). Mezzotint engraver. He engraved over 900 plates, of which two thirds are portraits, but he is also responsible for the large engraving A Shipwreck (1807) after Turner, and the first 20 published plates for the Liber Studiorum. A quarrel interrupted the collaboration with Turner, but engraver and artist were later reconciled. Charles Turner went on to engrave a further three published plates and one unpublished plate for the series, as well as a number of other engravings after Turner (see Rawlinson, The Engraved Work of J.M.W. Turner, volume 2, pp.209-211). For further biographical details see Engen, Dictionary of Victorian Engravers, pp.202-203, and Davenport, Mezzotints, pp. 167-68.
