English painter of Flemish birth. Trained in the Netherlands, Tillemans and his brother-in-law, Peter Casteels, went to England in 1708 to work for a picture dealer named Turner as copyists of Old Master paintings. He did well copying landscapes and made his own compositions. By 1711 he seems to have established his own painting practice and in that year became a founder-member of the Great Queen Street Academy, where he declared his speciality as 'landskip'. From 1708 until his death he lived and worked in England. Alongside John Wootton and James Seymour, he was one of the founders of the English school of sporting painting. //
