James Whistler was an American artist born in 1834, known for his contributions to the Aesthetic Movement. He is best recognized for his paintings, particularly "Arrangement in Grey and Black No. 1," commonly referred to as "Whistler's Mother." Whistler's work emphasized harmony and color, often focusing on the interplay of light and shadow. Whistler spent much of his life in Europe, especially in England and France, where he became a prominent figure in the art world. He was also a skilled etcher and a notable art critic, advocating for the idea that art should be appreciated for its beauty rather than its subject matter.
