Georges-Pierre Seurat was a French Neo-Impressionist painter in the late 19th century who developed the technique of pointillism. Pointillism involved applying small dots or points of pure color close together so that from a distance they visually blend in the eye of the observer. Seurat was inspired by scientific theories on color and contrast, and used this technique to carefully organize color on his canvases. He would labor for up to a year on preparatory studies before beginning a final painting using the pointillist method.
