Joseph Mallord William Turner RA (23 April 1775 – 19 December 1851) was an English Romantic landscape painter, watercolourist and printmaker. Turner was considered a controversial figure in his day, but is now regarded as the artist who elevated landscape painting to an eminence rivaling history painting.[1] Although renowned for his oil paintings, Turner is also one of the greatest masters of British watercolour landscape painting. He is commonly known as "the painter of light"[2] and his work is regarded as a Romantic preface to Impressionism. http://en.wikipedia.org/wiki/J._M._W._Turner
