Thomas Gainsborough
According To...

"Landscape was afterwards still farther debased by Vernet, Hakert, Jacob Moor and the English Wootton, the last of whom, without manual dexterity, left it in unredeemed poverty and coarseness… Then, with Wilson and Gainsborough, the high and genuine qualities of landscape appeared in England at a time when they were utterly unknown in any other part of the world."
