David Wolff is undoubtedly the most important Hague stipple engraver, although unfortunately little is known of his life and work. It is not known who taught Wolff the art of stippling on glass. He worked for some time in the studio of the painter Dirk van der Aa (1731–1809), who specialized in decorative painting on carriages and wallpaper. It was here that he learnt to portray the putti and other decorative elements found on his glasses, which clearly reveal van der Aa's influence. Only ten known glasses are signed by Wolff. Apart from the ever popular putti, Wolff's oeuvre also included a large number of portraits and superbly executed landscapes. The style of the engravings, the subject matter and the glasses themselves all support a dating of his work to circa 1775 and the year of his death in 1798 (see F.G.A.M. Smit, Uniquely Dutch eighteenth-century stipple-engravings on glass, Peterborough, 1993, pp. 14–16 for a more extensive biography of David Wolff).
