Industrial Boomtown: The Building of Donora, Pennsylvania - At the turn of the 20th century, Donora became the last of the great steel towns built along the Monongahela River, and it all seemed to happen overnight. When William H. Donner moved his National Tin Plate Company to the newly built industrial town of Monessen, in 1898, the area that would be Donora in three short years was mostly farmland and a small village called West Columbia. Donner quickly impressed the industrial elite of Pittsburgh and in 1899 formed the Union Improvement Company along with the Mellon brothers: Richard and Andrew, Henry Clay Frick and others with an eye toward creating another industrial complex across the river, one mile north of Monessen and about thirty miles south of Pittsburgh. As the mill and infrastructure of the town went up the population exploded with new arrivals, growing to nearly four thousand by 1901. Union Improvement thought of nearly every need of a new community except for housing for employees, creating a booming hotel and boarding house business. A large and diverse population poured into Donora to not only build and work at the mills but to also take part of the "American Dream" by starting their own business. Individual entrepreneurs opened everything and anything a new town might need or demand. The newcomers also built churches, a synagogue, ethnic and national social clubs, political and beneficial associations, and fraternal and civic associations. The community put a priority on education building schools that were a source of pride in the community. At the center of all this was the mill itself, the only reason the town even existed.
