Samuel Prout (/praʊt/; 17 September 1783 – 10 February 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. His nephew is John Skinner Prout
He was born at Plymouth, the fourth of fourteen children born to Samuel Prout Senior, a naval outfitter in the dockyard city, and Mary Cater. Attending Plymouth Grammar School he came under the influence of Headmaster Dr. John Bidlake who encouraged the young Prout and Benjamin Robert Haydon in their artistic apprenticeship. They spent whole summer days drawing the quiet cottages, rustic bridges and romantic watermills of the beautiful valleys of Devon. With John Britton, he made a journey through Cornwall to try his hand in furnishing sketches for Britton's Beauties of England. In 1803 he moved to London, where he stayed until 1812. Marrying Elizabeth Gillespie in 1810, they had four children; Rebecca Elizabeth (b. 1813), Elizabeth Delsey (b. 1817), Isabella Anne (b. 1820), and Samuel Gllespie (b. 1822).
In London, Prout saw new possibilities, and endeavoured to correct and improve his style by studying the works of the rising school of landscape. To earn a living, he painted marine pieces for Palser the printseller, took students, and published drawing books for learners. He was one of the first to use lithography.
