Georges Seurat was a French post-impressionist painter born in 1859 who developed the style of pointillism. He studied color theories and spent his career moving away from impressionism towards a more structured technique using science and dots of color. His most famous work Sunday Afternoon on the Island of La Grande Jatte from 1886, currently located at the Art Institute of Chicago, was his breakthrough piece that established his pointillist style which uses dots of paint that blend together in the viewer's eye. Seurat's innovative technique changed the course of impressionism and made him one of the most important post-impressionist artists.
