Jeannette, the Glass City, was the first industrial city in Westmoreland County. From Jeannette's founding in 1888 by Pittsburgh industrialist H. Sellers McKee, the city was destined for fame. Jeannette produced more glass in various forms than any other city in the world. At one time there were seven great glass factories in Jeannette, all producing glass that was shipped worldwide. Jeannette was a beautiful planned Victorian town, and the residents were proud of their city. A new form of correspondence became popular: the penny postcard. Jeannette features postcards showing the area's Victorian mansions, workers' row houses, factories, schools, churches, businesses, streets, and government buildings.
