This industry was born in the Lehigh Valley. David O. Saylor first made portland cement at Coplay in 1871. Here also was the first use of the rotary kiln process commercially Nov. 8, 1889. This region has continued to lead in the industry.
Portland Cement was orginially made in Britian in the 19th century. It looked like Portland stone, which is a type of stone quarried on the Isle of Portland, in Dorset.
