I was drawn into the Wikipedia piece on him which begins:
Samuel Prout (/praʊt/; September 17, 1783 – February 10, 1852) was one of the masters of British watercolour architectural painting. Prout secured the position of Painter in Water-Colours in Ordinary to King George IV in 1829 and afterwards to Queen Victoria. John Ruskin, whose work often emulated Prout's, wrote in 1844, "Sometimes I tire of Turner, but never of Prout". Prout is often compared to his contemporaries; Turner, Gainsborough, Constable and Ruskin, whom he taught.It is all worth reading and the art samples are lovely.
