Allentown Portland Cement Company

Allentown Portland Cement Company was an American cement manufacturer established in 1906. Its business centered on Portland cement and mortar cement, products used in construction and masonry. The company was associated with the Allentown area of Pennsylvania and completed its first manufacturing plant in Evansville, Pennsylvania, in 1910. This initial plant marked the transition from the company’s formation into operating production and provides the clearest documented location in its early history. The company later participated in consolidation within the American cement industry. In 1953, it acquired Valley Forge Cement Company, expanding its corporate interests beyond its original operating business. Seven years later, in 1960, Allentown Portland Cement Company was acquired by National Gypsum Company. The acquisition ended the company’s independent corporate existence, although the available reference material does not establish whether its plants, products, or trade name continued under National Gypsum ownership. The surviving information does not identify the company’s founder, detailed management team, headquarters address, production capacity, specific product grades, distribution network, financial performance, or exact date of final operational closure. It also does not establish whether the company operated under additional consumer-facing brands. Accordingly, the company is best understood as a historical regional cement producer whose documented corporate milestones include its 1906 founding, the 1910 completion of its first plant, the 1953 acquisition of Valley Forge Cement Company, and its 1960 acquisition by National Gypsum Company.

Allentown Portland Cement Company was formed in 1906 as an American producer of Portland and mortar cement. The company’s name connected it with the Allentown area of Pennsylvania and identified its principal industrial activity. Portland cement was a fundamental construction material, while mortar cement served masonry and related building applications. The company completed its first plant in Evansville, Pennsylvania, in 1910. This was the first specifically documented production facility in the available historical record. The source material does not provide the plant’s capacity, workforce, technology, raw-material sources, distribution territory, or the precise corporate relationship between the company’s Allentown identity and the Evansville facility. It nevertheless establishes that the business progressed from incorporation or formation to active manufacturing within four years. During the postwar period, the company expanded through acquisition. In 1953, it purchased Valley Forge Cement Company. The transaction indicates an effort to enlarge the company’s position in the cement sector, but the available sources do not specify the purchase price, assets transferred, facilities involved, or whether Valley Forge continued as a separate operating entity. In 1960, National Gypsum Company acquired Allentown Portland Cement Company. This transaction brought the cement manufacturer under National Gypsum ownership and ended its documented period as an independent company. The available material does not state whether the Allentown name was retained as a product or plant brand, whether the company was merged into another National Gypsum subsidiary, or when its production activities ultimately ceased. No reliable information in the supplied references identifies the company’s founder, senior executives, detailed ownership before 1960, public listing status, sales, financial results, environmental record, labor history, or later successor organization. The documented history is therefore limited but clear in outline: formation in 1906, completion of an initial Evansville plant in 1910, acquisition of Valley Forge Cement Company in 1953, and acquisition by National Gypsum Company in 1960.
