Georges Seurat was a French post-Impressionist painter and draftsman who is best known for his pioneering technique of Pointillism. Pointillism is a painting technique in which small, distinct dots of color are applied in patterns to form an image. Seurat's most famous work, A Sunday Afternoon on the Island of La Grande Jatte, exemplifies this technique. Georges Seurat is considered one of the most important figures in the development of modern art.
