James Abbott McNeill Whistler
James Abbott McNeill Whistler (; July 10, 1834 – July 17, 1903) was an American artist, active during the American Gilded Age and based primarily in the United Kingdom.
He was averse to sentimentality and moral allusion in painting, and was a leading proponent of the credo "art for art's sake". Finding a parallel between painting and music, Whistler entitled many of his paintings "arrangements", "harmonies", and "nocturnes", emphasizing the primacy of tonal harmony. His most famous painting is Arrangement in Grey and Black No. 1 (1871), commonly known as Whistler's Mother, the revered and oft-parodied portrait of motherhood. Whistler influenced the art world and the broader culture of his time with his artistic theories and his friendships with leading artists and writers.
