'We Want Clean Air' protest banner, Paddington. This statement outside homes in Gloucester Terrace, Paddington referred to the polluted air and its consequences to Londoners' health. Between 5 and 8 December 1952, a dense fog covered London. Thousands of Londoners died in the weeks immediately after this 'Great Smog', raising mortality rates far higher than average. Debate arose over whether or not these deaths were a result of the polluted fog. In 1956 The Clean Air Act, which attempted to curb smoke pollution, was passed.
