Mark Wayner (Weiner) was born into a Jewish family in Lomza, Poland in 1888 and immigrated to London with his parents in 1893, settling in the Jewish quarter in London's East End. He displayed an early flair for drawing and was a friend of Mark Gertler and David Bomberg, with whom he mixed at the Whitechapel Library and Art Gallery. After an apprenticeship, he studied at the Craft School (affiliated to the Royal College of Art) and then briefly at the Slade School of Fine Art (from 1909-10), assisted by a Jewish Education Aid Society grant (which was withdrawn due to poor attendance), although Bomberg and Jacob Epstein included his work in the so-called 'Jewish Section' in the important Whitechapel Art Gallery exhibition: Twentieth Century Art: a Review of Modern Movements in May 1914. Wayner quickly established a reputation as a caricaturist - some of his caricatures were reproduced in Colour magazine - and published two volumes of Celebrities in Caricature in 1931 and c. 1940, portraying contemporaraneous notables from the worlds of politics and the arts, including many Jewish subjects. He was a founder member of Ben Uri in 1915. His work was shown alongside fellow cartoonists Joss, Ross, Ralph Sallon, Walter Trier, Vicky and Victoria at a Ben Uri exhibition of Cartoons and Caricatures in 1950. He died in Saffron Walden in Essex in 1980.
