1. Jones & Laughlin Steel Company Marker
Inscription. Jones and Laughlin Steel Company. For over 140 years, the Jones and Laughlin Company (J&L) defined Pittsburgh. Its huge blast furnaces, open-hearth facilities, and neon J&L sign were landmarks for many Pittsburghers. The plant was located on this stretch of land and on a tract directly across the river. J&L expanded from a small iron puddling furnace in 1853 into a fully integrated mill by the twentieth century. Over the years, J&L produced iron and steel products that changed as a reflection of the needs of the times: nails, rails, automobile and machine parts, alloy plate for aircraft and tank armor, and artillery shells.
In 1968, J&L was purchased by the LTV Corporation. The mill continued to be a large presence in the region until its demise in 1984. The coke plant, however, continued to operate under the LTV banner until 1998. . This historical marker was erected by Rivers of Steel National Heritage Area. It is in Pittsburgh in Allegheny County Pennsylvania
