Traffic in smog at night, 1956 2017.36/4 and urban districts are shownTraffic in smog at night. Heavy smog was common in London in the 1950s and this photograph was taken only four years after the Great Smog of 1952, which claimed at least 8,000 lives, half of which in the immediate aftermath of the Smog. Following an investigation, Parliament passed the Clean Air Act of 1956, which marked London's move away from coal burning as the primary heating source to gas, oil and electricity.
