William Tassie (1777 – 26 October 1860) was a British gem engraver and cameo modeller of Scottish descent, who worked in London in the early 19th century.
[1] On 28 January 1805, Tassie won the Boydell Shakespeare Gallery and its painting collection in a lottery held to pay off the debts of its owner, John Boydell.
Tassie's three-guinea ticket won the top prize among the 22,000 sold.
[2] The painting collection and two reliefs by Anne Damer fetched a total of £6,181 18s.
He bequeathed to the Board of Manufactures, Edinburgh, an extensive and valuable collection of casts and medallions by his uncle and himself, along with portraits of James Tassie and his wife by the painter David Allan, and a series of watercolour studies by George Sanders from pictures of the Dutch and Flemish schools.
