David Garshen Bomberg was a British painter, and one of the Whitechapel Boys.
Bomberg was one of the most audacious of the exceptional generation of artists who studied at the Slade School of Art under Henry Tonks, and which included Mark Gertler, Stanley Spencer, C.R.W. Nevinson, and Dora Carrington. Bomberg painted a series of complex geometric compositions combining the influences of cubism and futurism in the years immediately preceding World War I; typically using a limited number of striking colours, turning humans into simple, angular shapes, and sometimes overlaying the whole painting a strong grid-work colouring scheme. He was expelled from the Slade School of Art in 1913, with agreement between the senior teachers Tonks, Frederick Brown and Philip Wilson Steer, because of the audacity of his breach from the conventional approach of that time.
