Founded by Andrew Carnegie in 1892, Carnegie Steel Company became the dominant force in Pittsburgh’s industrial landscape and a symbol of America’s rise as a global steel power. Built on innovation, efficiency, and relentless reinvestment, the company harnessed the Bessemer process and later open-hearth furnaces to produce steel on an unprecedented scale. Its Homestead Works and other Pittsburgh-area mills supplied the raw material for the nation’s railroads, skyscrapers, and bridges - literally building modern America. Carnegie sold the company to J.P. Morgan in 1901, forming U.S. Steel, cementing Pittsburgh’s identity as the “Steel City.”
