An artist, Finnish by birth, who settled in England and eventually, at the end of his life, emigrated to the United States, where he died. Spornberg painted a few silhouettes in black, on glass (see Section Three), but his most important achievement lies in his magnificent series of profiles painted in the 'Etruscan man-ner', to use his own description of a technique which he himself devised. These profiles are painted in line on a vermilion red base colour against a black background, on the under side of convex glass. He also painted a few profiles in two other styles in which the sitters' features are shown: profiles painted en grisaille on ivory, and profiles painted on card.
Spornberg is recorded (without an initial) by Mills and (either with the wrong initial, or as one of two brothers) by other authorities. The present entry is based on the fullest account of the artist and his family yet published: in my own book, Jacob Spornberg: Eighteenth Century Artist from Finland (London, 1971).
