Born at Lambeth, Surrey in 1871, the son of Edmund Turner and his wife Sarah Ann née Staff who had previously lived in Norwich, Turner received artistic training through a sequence of some thirty letters dated 1908-1913 from Spencer Gore while working as a stockbroker's clerk. The correspondence was used by Esther Freud in her novel The Sea House. East Anglia was clearly a favourite of his, and he married a Norwich girl, Frances Elizabeth Birch at Norwich on 25 November 1893, around the time that he added the second name of Doman. Gore proposed his pupil John Doman Turner, who worked in pencil, charcoal, chalk, and watercolour but not in oils, as one of the 16 members of the Camden Town Group when it formed in 1911, and Turner Doman painted in Walberswick and Southwold areas of Suffolk from 1911 until at least 1936. His works included the 'Walberswick Scroll' a dioramic view of this Suffolk village painted in 1931 which includes every property in Walberswick on a scroll 21 inches high by 123 feet long. His extant drawings of Ilfracombe, Tenby, Eastbourne and Folkestone probably reflect holidays in these seaside towns. He also painted around Mitcham, Surrey before the First World War particularly on the annual visit of the fun-fair on Mitcham Common which were exhibited in London. He died at his Streatham home on 3 January 1938, and a major exhibition of his work was mounted by the University of Hull in 1997.
