November 24, 1966. Millions of spectators flood Broadway in New York City to watch the Macy’s Day Parade on Thanksgiving morning. The iconic floats – Superman, Popeye, Smokey the Bear – are set against a grey sky that can only be described as noxious. A smog of pollutants is trapped over New York City, and it will ultimately kill nearly 200 people. How did the 1966 Thanksgiving Smog help usher in a new era of environmental protection? And how have we been thinking about environmental disasters all wrong?Special thanks to our guest Professor Frank Uekotter, author of The Age of Smoke.
