, Birmingham – where Cox lived from 1841 until his death in 1859 – pictured by his son
David Cox Jr. In May 1840 Cox wrote to one of his Birmingham friends: "I am making preparations to sketch in oil, and also to paint, and it is my intention to spend most of my time in Birmingham for the purpose of practice." Cox had been considering a return to
painting in oils since 1836 and in 1839 had taken lessons in oil painting from
William James Müller, to whom he had been introduced by mutual friend
George Arthur Fripp. Hostility between the
Society of Painters in Water Colours and the
Royal Academy made it difficult for an artist to be recognised for work in both watercolour and oil in London, however, and it is likely that Cox would have preferred to explore this new medium in the more supportive environment of his home town. By the early 1840s his income from sales of his watercolours was sufficient to allow him to abandon his work as a drawing master, and in June 1841 he moved with his wife to Greenfield House in
Harborne, then a village on Birmingham's south western outskirts. It was this move that would enable the higher levels of freedom and experimentation that were to characterise his later work. in 1855. In Harborne, Cox established a steady routine – working in watercolour in the morning and oils in the afternoon. He would visit London every spring to attend the major exhibitions, followed by one or more sketching excursions, continuing the pattern that he had established in the 1830s. From 1844 these tours evolved into a yearly trip to
Betws-y-Coed in
North Wales to work outdoors in both oil and watercolour, gradually becoming the focus for an annual summer
artists colony that continued until 1856 with Cox as its "presiding genius". Cox's experience of trying to exhibit his oils in London was short and unsuccessful: in 1842 he made his only submission to the
Society of British Artists; one oil painting was exhibited at each of the
British Institution and the
Royal Academy in 1843; and two oil paintings were exhibited at the Royal Academy in 1844 – the last that would be exhibited in London during his lifetime. Cox showed regularly at the Birmingham Society of Arts and its successor, the Birmingham Society of Artists, becoming a member in 1842. Cox suffered a
stroke on 12 June 1853 that temporarily paralysed him, and permanently affected his eyesight, memory and coordination. By 1857 however, his eyesight had deteriorated. An exhibition of his work was arranged in 1858 by the Conversazione Society
Hampstead, and in 1859 a retrospective exhibition was held at the German Gallery
Bond Street, London. Cox died several months later. He was buried in the churchyard of
St Peters,
Harborne, Birmingham, under a
chestnut tree, alongside his wife Mary. ==Work==
