The housing question lay at the heart of the Viennese project of municipal socialism. Facing a collapse in the housing market after the First World War, the social-democratic administration built nearly 64,000 new homes between 1919 and 1934, providing accommodation for around 200,000 people. The programme was the envy of Europe and was frequently praised by British Labour politicians. However, whilst impressive, the number of homeless in the city continued to rise, tripling between 1924 and 1934. This is one of a series of photographs by Tudor-Hart of a city slum, suggesting she was keen to document an aspect of Viennese life too often avoided by official publications.
