London Fog in the early 20th Century … Known as Pea Soup Fog, a problem for centuries derived from the use of coal for home heating and industrial processes. The ‘Pea Souper’ events seemed to culminate with the Great Smog of London in December of 1952 (the last 2 photos here) which resulted in thousands of deaths and led to the creation of the Clean Air Act in 1956 #londonfog #londonsmog #peasoupfog #peasouper #thegreatlondonsmog #greatsmogof1952 #fog #smog #photography #fotografia #fotografie #london #20thcenturylondon #coal #londonhistory
