History

In 1794, the Whiskey Insurrectionists held several meetings at Fells Church, approximately 1 mile (1.6 km) east of Donora.

A trolley line opened in Donora on December 15, 1901, linking First and McKean, and Fifteenth Street and Meldon. It was extended in 1911 to Black Diamond to connect to the Charleroi to Pittsburgh interurban trolley. The line was abandoned on May 5, 1953.

The town was the scene of the infamous Donora Smog of 1948. Between October 26 and October 31, 1948, an air inversion trapped industrial effluent (air pollution) from the American Steel and Wire plant and Donora Zinc Works. During this spike in air pollution, 6,000 people suffered respiratory problems and extreme discomfort. "In three days, 20 people died... After the inversion lifted, another 50 died, including Lukasz Musial, the father of baseball great Stan Musial. Hundreds more finished the rest of their lives with damaged lungs and hearts." The incident made national headlines. Today, the town is home to the Donora Smog Museum, which tells the impact of the Donora Smog on the air quality standards enacted by the federal government in subsequent years.
