Alfred Aaron Wolmark (28 December 1877 – 6 January 1961) was a painter and decorative artist. He was a Post-Impressionist and a pioneer of the New Movement in Art.
Wolmark was born in Warsaw, Poland, into a Jewish family, who were amongst the many subsequently fleeing the pogroms of Eastern Europe. The family moved to Devon when he was six and in 1894, he became a British citizen. When Wolmark moved to London in the 1890s, he began training at the Royal Academy Schools.
His early brightly coloured Breton scenes are characterized by bold, geometric patterning and vivid colour, which owed much to the influence of Post-Impressionism. He was a close friend of the sculptor Henri Gaudier-Brzeska, and the two artists made portraits of one another. In addition to painting, Wolmark created stained glass, decorative painted vases, ballet designs for Diaghilev, and illustrated Israel Zangwill's complete works.
Wolmark exhibited widely during his lifetime in London, New York, and Paris.
