Signac, Paul

(pōl sēnyäk´), 1863–1935, French neoimpressionist painter. First influenced by Monet, he was later associated with Seurat in developing the divisionist technique. Interested in the science of color, he painted with a greater intensity and with broader strokes than Seurat. In such vigorous, colorful works as Port of St. Tropez (1916; Brooklyn Mus., New York City) Signac broke through the confines of neoimpressionist theory. He wrote a treatise, D'Eugène Delacroix au néo-impressionisme (1889), long considered the foremost work on the school.
