Andrew Carnegie is recognized as the king of the steel industry primarily due to his role in revolutionizing steel production in the United States during the late 19th century. He introduced innovative manufacturing processes, such as the Bessemer process, which allowed for the mass production of steel at a lower cost. This significantly contributed to the industrial growth of the nation and helped establish the United States as a leading steel producer.

Carnegie's business model focused on vertical integration, where he controlled every aspect of the steel production process, from raw material extraction to transportation and distribution. His company, Carnegie Steel, became one of the largest and most profitable steel manufacturers in the world.

Furthermore, Carnegie's philanthropic efforts after selling his company emphasized his lasting impact on American society, as he donated vast sums of money to education and public libraries. His legacy is closely tied to the expansion of the steel industry and the broader industrial economy of the United States.
