Joseph Mallord William Turner (23 April 1775 – 19 December 1851), known in his time as William Turner, was an English Romantic painter, printmaker and watercolourist. He is known for his expressive colourisations, imaginative landscapes and turbulent, often violent marine paintings.

He left behind more than 550 oil paintings, 2,000 watercolours, and 30,000 works on paper. He was championed by the leading English art critic John Ruskin from 1840, and is today regarded as having elevated landscape painting to an eminence rivalling history painting.

Joseph Mallord William Turner was born on 23 April 1775 and baptised on 14 May. He was born in Maiden Lane, Covent Garden, in London, England. His father William Turner was a barber and wig maker. His mother, Mary Marshall, came from a family of butchers. A younger sister, Mary Ann, was born in September 1778 but died in August 1783.
