George Knapton was a portrait painter in oils and crayons. He was born in London and trained at the St Martin’s Lane Academy; he was also apprenticed to Jonathan Richardson the elder. Knapton was a founding member the Society of Dillettanti in 1736, and painted twenty-three portraits of the members, mostly in fancy dress. He also published a paper on the recent discovery of Herculaneum in 1740. He resigned as a member of the Society in 1763, but seems to have given up painting c.1755. He became surveyor and keeper of the King’s pictures in 1765.
