Combatting Air Pollution in Southern California in the 1950s
Smog was an obvious problem in Los Angeles by the early 1950s. What caused it? What should be done about it?
Science History Institute
Join Institute research curator Roger Turner as he discusses the experiments conducted by chemists Arnold Beckman and Arie Haagen-Smit that revealed the invisible culprit: ozone. This discovery led to a coalition of scientists, industry leaders, bureaucrats, and activists to create laws that eventually reduced ugly brown smog, but did little to reduce other harms associated with air pollution.
