Joseph Wilton RA (16 July 1722 – 25 November 1803) was an English sculptor. He was one of the founding members of the Royal Academy in 1768, and the academy's third keeper. His works are particularly numerous memorialising the famous Britons in Westminster Abbey.
Born the son of an ornamental plasterer in the Charing Cross area of London, his father had sculpted the ceilings of the Foundling Hospital there. His father wished him to be a civil engineer but he strongly desired to be a sculptor.
Wilton initially trained under Laurent Delvaux at Nivelles, in present day Belgium. In 1744 he left Nivelles and went to the Academy in Paris to study under Jean-Baptiste Pigalle. In 1752 he went to Italy with his sculptor friend Louis-François Roubiliac to learn to sculpt in marble, and stayed for seven years, living first in Rome and then in Florence. Whilst in Rome he met and befriended his first patron, William Locke of Norbury, who thereafter accompanied Wilton on his tour of Italy. Like many other artists of the day, he studied antiquities, and made numerous plaster casts and marble copies of classic works – many of these later formed the collection of Charles Lennox, 3rd Duke of Richmond at Richmond House in west London. A marble bust of the physician and scholar Antonio Cocchi, carved by Wilton in 1755, his last year in Italy, is in the collection of the Victoria and Albert Museum. Influenced by Wilton's study of antique busts, it was considered by Margaret Whinney to be one of Wilton's most distinguished works.
Once back in London, Wilton was named co-director of Lennox's Richmond House gallery, and established a workshop. He built up a considerable practice, making busts and monuments, including the memorial to James Wolfe in Westminster Abbey. He made at least two marble busts of Oliver Cromwell, which he showed at the Society of Artists, in 1761 and 1761, basing the likeness on a cast of Cromwell's face. One marble version, and the terracotta model for it, is in the collection of the Victoria and Albert Museum.
In 1761, he was first commissioned to produce a statue of King George III. Similar commissions followed, including one in 1766 from New York City. This massive statue portrayed the king on horseback in Roman garb, and was cast in lead and gilded before being shipped to America and erected at Bowling Green, near the tip of Manhattan in August 1770. It did not last long, being torn down by patriots in July 1776.
In 1768, when Wilton was perhaps at the peak of his powers, he was elected a founder member of the Royal Academy. However, that year also saw him inherit his father's fortune and the new wealth diverted him away from sculpture to a life of dissolution. In 1786 he was forced to sell most of his possessions and in 1793 he was officially declared bankrupt. In 1790 he was appointed Keeper of the Royal Academy, a post he kept until his death in 1803. He was buried at Wanstead Church in east London.
