In 1819 he moved to Hampstead Heath on the outskirts of London. By this time his father had died, so he was more financially secure. He was now producing his best work, including ‘The Haywain’ in 1821. The work was based on many sketches he had produced, many of which still survive. In 1824 ‘The Haywain’ was exhibited in Paris, where it won a gold medal. The painting caused a stir amongst the French art critics, who were astonished by its freshness. In his later years he lectured, still trying to popularise landscape painting, but he died in 1837 with none of the fame he now has.
