A.M. Byers established the A.M. Byers Company in Pittsburgh making rod-iron pipes and was responsible for innovations in iron production control. In 1864, he established a business in the Southside area of Pittsburgh making rod-iron pipes. Originally the Graff, Byers Company, it was renamed the A.M. Byers Company in 1876. The first plant was in Southside with offices in the Clark building; at various times, the company had five plants, three in Pennsylvania and two in Ohio. The Ambridge plant opened in 1930. In 1956, the Ohio-based General Tire and Rubber Company acquired control over A.M. Byers. The Ambridge plant began to shut down in 1960, with the Southside plant closing in 1966. The company closed in 1969.
