“Sunday Afternoon on the Island of La Grande Jatte,” originally ridiculed, became the most famous work of Georges Seurat (1859 – 1891), defining him as an extraordinary artist and scientist. Seurat pioneered neo-Impressionism, using complex, scientifically based lines and geometry which gave his works order and unity. Innovating Pointillism, a meticulous style incorporating tiny points of pure color, “La Grande Jatte” contained over 40 figures, a detailed background, and took Seurat nearly two years to finish.
