Industry
David Oliver Saylor, born on October 20, 1827, in Hanover Township, Lehigh County, organized the Coplay Cement Company in 1866 to manufacture natural cement. He soon began experiments in 1871 to produce Portland cement and was granted a patent on his process. With the help of John W. Eckert, the process was improved, and in 1876 Saylor’s Portland Cement received an award at the Centennial Exposition. He was the moving spirit in the founding of the American Portland Cement industry. He died on July 21, 1884.
