The architecture and engineering firm of Ballinger & Perrot was established in 1901 by Walter F. Ballinger and Emile G. Perrot. It succeeded the firms of Geissinger & Hales and Hales & Ballinger and was succeeded by the Ballinger Co. which began in 1920 after Walter F. Ballinger bought out the interests of his partner Emile G. Perrot. Ballinger & Perrot built upon the industrial building interests of the earlier firms but also expanded into workers housing, especially that associated with company or federal housing operations. Chief among these works was the village constructed for the American Viscose Company in Marcus Hook, PA. However, the partners were not limited to industrial building, but instead completed churches, schools, and commercial structures and pioneered in the use of reinforced concrete. During World War I Ballinger & Perrot also maintained a 125-person office in New York, supervised by Carl deMoll.
