The Great Smog of 1952 enveloped central London in a pea souper, seriously hampering the city for the best part of a week. Some who ignored warnings not to venture out found themselves falling into the Thames or getting run over. Many more died of breathing difficulties. It's thought that 4,000 Londoners perished in just five days.
