What was the Bessemer steel converter how did this invention shape us history?

The Bessemer steel converter, invented by Henry Bessemer in the 1850s, was a revolutionary method for mass-producing steel by blowing air through molten iron to remove impurities. This innovation significantly reduced the cost and time required to produce steel, leading to its widespread use in construction, railroads, and machinery. The availability of cheaper steel facilitated rapid industrialization in the United States, contributing to economic growth and the expansion of infrastructure during the late 19th and early 20th centuries, shaping modern American society.
