Andrew Carnegie Steel Company

Andrew Carnegie Steel Company was a major American steel producer founded by Andrew Carnegie in the late 19th century. It became one of the largest and most efficient steel manufacturing firms, leveraging innovative techniques like the Bessemer process to produce steel more cheaply and quickly. The company supplied materials for many infrastructure projects such as railroads, bridges, and buildings, fueling America's industrial growth. In 1901, Carnegie sold the company to J.P. Morgan, who formed U.S. Steel, marking a significant consolidation of the steel industry. Carnegie's success helped establish the United States as a leading steel producer globally.
