Paul Signac (1863–1935) was a French Neo-Impressionist painter who, working with Georges Seurat, helped develop the Pointillist style.
In 1884 Paul Signac met Claude Monet and Georges Seurat. He became Seurat's faithful supporter, friend and heir with his description of Neo-Impressionism and Divisionism method. Under his influence he abandoned the short brushstrokes of Impressionism to experiment with scientifically juxtaposed small dots of pure color, intended to combine and blend not on the canvas but in the viewer's eye, the defining feature of Pointillism.
In 1886 Signac met Vincent van Gogh in Paris. In 1887 the two artists regularly went to Asnières-sur-Seine together, where they painted such subjects as river landscapes and cafés. In March 1889, Signac visited Vincent van Gogh at Arles.
