Ozias Humphry (or Humphrey) (8 September 1742 – 9 March 1810) was a leading English painter of portrait miniatures, later oils and pastels, of the 18th century. He was elected to the Royal Academy in 1791, and in 1792 he was appointed Portrait Painter in Crayons to the King (i.e. pastels).
Humphry is the spelling Ozias himself used in his signature on the backing card of his miniature of Charlotte, Princess Royal (1769; Windsor Castle). This is also the spelling given in the catalogues of the annual exhibitions of the Royal Academy from 1779 to 1795. The different spelling in the far more common form of Humphrey may originally well be due to a mistake but was already in use during his own lifetime. It appears thus in the Royal Academy catalogues for the years 1796 and 1797 as well as in the writings of Horace Walpole and John Thomas Smith. Humphry is the generally used spelling today.
Born and schooled in Honiton, Devon, Humphry was attracted by the gallery of casts opened by the Duke of Richmond and came to London to study art at Shipley's school. He also studied art in Bath (under Samuel Collins, taking over his practice in 1762); in Bath, he lodged with Thomas Linley. As a young artist, his talent was encouraged by Thomas Gainsborough and Sir Joshua Reynolds, among others. His problems with his sight, which ultimately led to blindness, began in the early 1770s and forced him to paint larger works in oils and pastel.
