John Robert Cozens

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

The son of the Russian-born drawing master and watercolourist, Alexander Cozens, John Robert Cozens was born in London. He studied under his father and began to exhibit some early drawings with the Society of Artists in 1767. In 1776, he displayed a large oil painting at the Royal Academy in London. Between 1776 and 1779 he spent some time in Switzerland and Italy, where he drew Alpine and Italian views, and in 1779 he returned to London. In 1782 he made his second visit to Italy, accompanied by the author William Beckford, spending much time at Naples. In 1783 he returned to England. In 1789 he published a set of Delineations of the General Character ... of Forest Trees. He submitted his work to the Royal Academy but it was entirely rejected, being judged as "not proper art". At the age of 42, three years before he died, he suffered a nervous breakdown and was committed to the Bethlem Royal Hospital asylum. The chief physician there was Dr. Thomas Monro who, also being a keen art collector, recognised Cozens' brilliance and bought his collection. Cozens died in London.

Cozens executed watercolors in curious atmospherical effects and illusions which had some 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 called him "the greatest genius that ever touched landscape." On the other hand, Cozens never departed from his primitive, almost rudimentary, manner of painting, which causes several of his works to look very like coloured engravings.

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.
