Georges Seurat was a French post-Impressionist artist. He is best known for devising the painting techniques known as chromoluminarism as well as pointillism. While less famous than his paintings, his conté crayon drawings have also garnered a great deal of critical appreciation. Seurat's artistic personality combined qualities that are usually supposed to be opposed and incompatible: on the one hand, his extreme and delicate sensibility, on the other, a passion for logical abstraction and an almost mathematical precision of mind. His large-scale work A Sunday Afternoon on the Island of La Grande Jatte (1884–1886) altered the direction of modern art by initiating Neo-impressionism, and is one of the icons of late 19th-century painting.
