Born in Warsaw, he was taken to the East End of London as a child and studied in the Royal Academy Schools. He made his reputation at the Whitechapel Art Exhibition of 1906, where his work was praised by perceptive art critics. In his early period, he painted Whitechapel scenes and Rembrandtesque studies of Jewish subjects, such as rabbis and talmudic students. Later he developed into a brilliant colourist. His use of colour was so bright that in an exhibition of the International Society of Artists no English painter dared hang work next to his. His work was finally placed next to Van Gogh's. Wolmark did portraits of many noted literary figures and, in 1925, provided illustrations for an edition of the works of Israel *Zangwill. Wolmark held his first solo exhibition at Bruton Galleries in 1905. He soon began to exhibit on the continent and in America. He taught for some time at the Slade School of Fine Art in London. The works of this highly regarded artist can be seen in many collections, including those of The Tate Gallery and the National Portrait Gallery. A retrospective exhibit of Wolmark's work was held at London's Ben-Uri Gallery in 2004.
