Dictionary of National Biography, 1885-1900/Seaton, John Thomas
SEATON, JOHN THOMAS (fl. 1761–1806), portrait-painter, was son of Christopher Seaton, a gem-engraver, who was a pupil of Charles Christian Reisen [q. v.], and died in 1768. Seaton was a pupil of Francis Hayman [q. v.], and also studied in the St. Martin's Lane academy. He and his father were both members of the Incorporated Society of Artists, and signed their declaration roll in 1766. He resided for some time at Bath, whence he sent portraits to the exhibition of the society, and in 1774 he exhibited portraits at the Royal Academy. His portraits were usually small full-lengths in a landscape. He subsequently went to Edinburgh, where he practised with repute as a portrait-painter, and was living in 1806. A portrait by him of Walter Macfarlan (d. 1767) of Macfarlane is in the Scottish National Portrait Gallery.
