Which company did Andrew Carnegie found?

• A. Ford Motor Company
• B. Standard Oil Company
• C. Carnegie Steel Company
• D. U.S. Steel Corporation

Answer: (C)

Andrew Carnegie founded the Carnegie Steel Company, which played a crucial role in the U.S. steel industry during the late 19th century. Carnegie Steel became one of the largest and most successful steel manufacturers in the world, significantly contributing to the rapid industrialization of the United States. The company utilized innovative production methods, such as the Bessemer process, which allowed for the mass production of steel, ultimately leading to lower costs and increased availability. Carnegie's business practices and philanthropic efforts, particularly his advocacy for libraries and education, also left a lasting legacy in American society.

The other companies listed represent significant figures in American industrial history but are associated with different founders. Ford Motor Company was founded by Henry Ford, who revolutionized the automobile industry with assembly line production. Standard Oil Company was established by John D. Rockefeller and became synonymous with monopolistic practices in the oil industry. U.S. Steel Corporation was formed later when J.P. Morgan combined Carnegie Steel with several other steel companies, reflecting the evolution of the industry beyond Carnegie's original enterprise.
