The Mad Gasser of Mattoon terrified a small Illinois town in 1944, and no one was ever caught.

The Donora Smog Disaster of 1948 remains one of the deadliest air pollution disasters in American history. In the small steel town of Donora, Pennsylvania, a deadly cloud of industrial pollution became trapped in the valley for five days, leaving thousands sick and over twenty people dead.

In this episode of Yore Town: Small Towns, Big Stories, we dive deep into the shocking true story of the Donora Smog Disaster — a forgotten tragedy that changed environmental laws in the United States forever. What started as a normal autumn week in a hardworking steel town quickly turned into a public health catastrophe when a rare weather event trapped toxic emissions from local factories.
