At the beginning of the 20th century, signif-icant pieces in the foundation of America™s Industrial Revolution were established in the Lehigh Valley of Eastern Pennsylvania. Iron and steel, important products to the early development of our continent, were produced in Bethlehem, PA, and the first production of portland cement in North America took place in Coplay, PA. The Lehigh Portland Cement Company was founded in Allen-town in 1897, and cement production is still an important industry in the area. Several support businesses and professions, as well as Lehigh University, resided in the valley to provide engin-eering, design, testing, and manufacturing services for the production of cement and steel. Also early in the century, in 1904, the American Concrete Institute (ACI) was established, and the Portland Cement Association was formed in 1916.
