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, at the age of 18, deciding to pursue a career as a painter, after attending an exhibit of Monet's work. He sailed on the Mediterranean Sea, visiting the coasts of Europe and painting the landscapes he encountered. In later years, he also painted a series of watercolors of French harbor cities.
