Paul Victor Jules Signac (11 November 1863 – 15 August 1935) was a French Neo-Impressionist painter who, working with Georges Seurat, helped develop the Pointillist style.

Paul Signac was born in Paris on 11 November 1863. He followed a course of training in architecture before deciding at the age of 18 to pursue a career as a painter after attending an exhibit of Monet's work; he met both Monet and Seurat in 1884. He was struck by the systematic working methods of Seurat and by his theory of colours and 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 colour, intended to combine and blend not on the canvas but in the viewer's eye, the defining feature of Pointillism. Many of Signac's paintings are of the French coast.He left the capital each summer, to stay in the south of France in the village of Collioure or at St. Tropez.
