John Robert Cozens

John Robert Cozens (1752 – 14 December 1797) was a British draftsman and painter of romantic watercolour landscapes.

Cozens executed watercolors in curious atmospheric effects and illusions which had an influence on Thomas Girtin and J.M.W. Turner. Indeed, his work is full of poetry. There is a solemn grandeur in his Alpine views and a sense of vastness, a tender tranquility and a kind of mystery in most of his paintings, leaving parts in his pictures for the imagination of the spectator to dwell on and search into. John Constable described Cozens as "the greatest genius that ever touched landscape."

In June 2010 Cozen's Lake Albano (c.1777) sold at auction, at Sotheby's in London, for £2.4 million, a record for any 18th-century British watercolour.
