Paul Signac (1863–1935) was a French Neo-Impressionist painter renowned for co-developing the technique of Pointillism alongside Georges Seurat. Born in Paris, Signac initially pursued architecture but shifted to painting after encountering Claude Monet's work. Influenced by contemporary color theories, he adopted a method of applying small, distinct dots of pure color to his canvases, allowing optical blending to occur in the viewer's eye—a hallmark of Pointillism. Signac's oeuvre predominantly features luminous seascapes and harbor scenes, inspired by his extensive sailing along the Mediterranean coast. A committed anarchist, he infused his art with ideals of harmony and social progress. Beyond his paintings, Signac was an influential art theorist, authoring From Eugène Delacroix to Neo-Impressionism in 1899, and served as president of the Société des Artistes Indépendants from 1908 until his death, championing avant-garde artists and movements.
