Donora Smog Museum

In Donora, Pennsylvania, the Donora Smog Museum preserves the history and archival record of the 1948 air inversion in which smog containing fluorine settled over the mill town and killed 20 people. In a community shaped by U.S. Steel's Donora Zinc Works and the American Steel & Wire plant, the disaster became a defining part of local industrial history. Opened in 2008 in an old storefront on McKean Avenue, the museum emphasizes documentation and memory, including a digital primary-source collection developed with California University of Pennsylvania. Donora's deadly 1948 smog is widely linked to the rise of the U.S. clean-air movement and the later Clean Air Act.
