PQ Corporation photographic collection

About this collection

Joseph Elkinton began the Elkinton Company in 1831 as a Philadelphia candle and soap shop. After successfully marketing synthetic silicate-based soap during the Civil War, the company acquired a new plant in Anderson, Indiana, and began manufacturing lye, fertilizers, oils, greases, adhesives, fiber, and wall board. In 1888, the company name changed to the Philadelphia Quartz Company, and, in 1978, the name changed again to PQ Corporation when company headquarters moved to Valley Forge, Pennsylvania. This collection has not been digitized in its entirety. The online collection largely consists of images of unidentified employees dating from approximately 1860 to 1940.
