Joseph Mallord William Turner (1775-1851) was not only Britain's greatest painter but arguably the finest landscape and marine painter ever. Turner was enormously prolific, producing some 550 oil paintings, over 2,000 highly detailed and finely finished watercolours, and some 30,000 works on paper. His bequest to the nation of much of this output is without doubt the greatest artistic legacy ever bestowed upon the United Kingdom. It is housed in Tate Britain, London.
