The Pittsburgh and Lake Erie Railroad, also known as the "Little Giant", was formed on May 11, 1875. Company headquarters were located in Pittsburgh, Pennsylvania. The line connected Pittsburgh in the east with Youngstown, Ohio, in the Haselton neighborhood in the west and Connellsville, Pennsylvania, to the east. It did not reach Lake Erie until the formation of Conrail in 1976. The P&LE was known as the "Little Giant" since the tonnage that it moved was out of proportion to its route mileage. While it operated around one tenth of one percent of the nation's railroad miles, it hauled around one percent of its tonnage. This was largely because the P&LE served the steel mills of the greater Pittsburgh area, which consumed and shipped vast amounts of materials. It was a specialized railroad, deriving much of its revenue from coal, coke, iron ore, limestone, and steel. The eventual closure of the steel mills led to the end of the P&LE as an independent line in 1992.

The Harmony Society was a Christian theosophy and pietist society founded in Iptingen, Germany, in 1785. Due to religious persecution by the Lutheran Church and the government in Württemberg, the group moved to the United States, where representatives initially purchased land in Butler County, Pennsylvania. On February 15, 1805, the group of approximately 400 followers formally organized the Harmony Society, placing all their goods in common.
