Sir William Beechey was a leading English portraitist during the golden age of British painting.

Beechey was born at Burford, Oxfordshire, on 12 December 1753, the son of William Beechey, a solicitor, and his wife Hannah Read. Both parents died when he was still quite young, and he and his siblings were brought up by his uncle Samuel, a solicitor who lived in nearby Chipping Norton.

Beechey was admitted to the Royal Academy Schools in 1772, where he is thought to have studied under Johan Zoffany. He first exhibited at the Academy in 1776.

In 1782, he moved to Norwich, where he gained several commissions, including a portrait of Sir John Wodehouse and a series of civic portraits for St. Andrew's Hall, Norwich. By 1787, he had returned to London, and in 1789, he exhibited a celebrated portrait of John Douglas, Bishop of Carlisle (now in Lambeth Palace).

Beechey's style perfectly suited the conventional taste of the royal family, and in 1793, he was commissioned to paint a full-length portrait of Queen Charlotte and subsequently named as her official portrait painter. That same year, he was elected as an associate member of the Royal Academy.
