Sir William Beechey (1753-1839) was a leading English portrait painter whose straightforward, carefully finished style won him lasting royal patronage during the "golden age" of British portraiture. Born in Burford, Oxfordshire, he initially trained as a lawyer, his upbringing overseen by an uncle keen to secure him a respectable profession, but a chance acquaintance with students of the Royal Academy Schools drew him instead towards painting, and he entered the Schools himself in 1772, reportedly studying under Johan Zoffany. He exhibited at the Academy from 1776 and moved to Norwich in the early 1780s, where he built a local practice that included civic portraits for St Andrew's Hall, before returning to London around 1787, at a moment when the deaths and retirements of Gainsborough and Reynolds had left something of a vacuum at the top of English portraiture.
Beechey's reputation grew steadily through the 1780s, and in 1793 a portrait that had initially been rejected by the Royal Academy came to the attention of George III after an aggrieved sitter showed it to him directly; both the King and Queen Charlotte were sufficiently taken with Beechey's plain, unpretentious style that he was appointed portrait painter to the Queen that same year and elected an Associate of the Royal Academy soon afterwards. Royal commissions multiplied rapidly, and in 1798 Beechey was elected a full Academician and knighted by George III following the King's evident delight with Beechey's ambitious equestrian composition George III and the Prince of Wales Reviewing Troops. His portraits from this period, close in spirit to the livelier, more colourful manner of his younger rivals John Hoppner and Thomas Lawrence, are generally considered his finest. Beechey fell temporarily from royal favour in 1804, a lapse the diarist Joseph Farington attributed to the King's declining health, though royal patronage resumed around 1813 with his appointment as portrait painter to the Duke of Gloucester, and he was later named principal portrait painter to William IV in 1830.
The portrait by Beechey held by John Mitchell Fine Paintings exemplifies the restrained, carefully observed manner that distinguished his work from the bolder theatricality of contemporaries such as Lawrence, and situates the gallery's holdings within the mainstream tradition of English portraiture that flourished either side of 1800.
