Tish Murtha had an extensive exhibition of her work at the Photographers Gallery last year.
After studying photography in Newport she returned to the North East to document the social deprivation and instability in Britain. The kids jumping out of the window is from the Elswick Kids series she took immediately after completing her studies. Throughout her career she particularly focused on youth unemployment. Her pictures were so stark that it eventually was raised as a subject for debate in the House of Commons, in 1981.
