Joseph Mallord William Turner
(23 April 1775 – 19 December 1851) was an English Romantic landscape painter, watercolourist and printmaker, whose style can be said to have laid the foundation for Impressionism. Although Turner was considered a controversial figure in his day, he is now regarded as the artist who elevated landscape painting to an eminence rivalling history painting.
His work was exhibited when he was still a teenager. His entire life was devoted to his art. Unlike many artists of his era, he was successful throughout his career.
Turner's will, which was under litigation for many years, left more than 19,000 watercolors, drawings, and oils to the British nation. Most of these works are in the National Gallery and the Tate Gallery, London. Many of Turner's oils have deteriorated badly.
