Dictionary of National Biography, 1885-1900/Hayes, John (1786?-1866)
HAYES, JOHN (1786?–1866), portrait-painter, born about 1786, first appears as an exhibitor in the Royal Academy in 1814. He continued to exhibit up to 1851; his contributions were chiefly portraits, though he occasionally sent a subject-picture. Hayes had considerable practice as a portrait-painter, and died in 1866, aged 80. In the National Portrait Gallery there is a portrait by Hayes of Miss Agnes Strickland, painted in 1846, and engraved by F. C. Lewis, as frontispiece to her ‘Lives of the Queens of England’ (1851).
