The Carnegie Building, also known as the Carnegie Steel Building, was a high-rise building in Pittsburgh, Pennsylvania. The structure was completed in 1895, and stood as the first steel-framed skyscraper in Pittsburgh upon completion. The building served as the world headquarters of Carnegie Steel Company,[1] a steel producing company of the late 19th century created by industrialist and phialnthropist Andrew Carnegie to manage steel mills in the city. It was torn down in 1952.
The Carnegie Building was an early example of Chicago school architecture in Pittsburgh,[2] and was designed by the architectural firm Longfellow, Alden & Harlow.[3] It rose 13 floors in height, and stood as the first steel-framed skyscraper in Pittsburgh[4] and one of the first steel-cage structured buildings in the world.[3]
