Explanation

Henry Bessemer invented the Bessemer process in 1856, the first inexpensive industrial method for mass-producing steel from molten pig iron. The process involved blowing air through molten iron to burn off impurities, creating steel. This revolutionized construction and engineering by making steel affordable for bridges, railways, and buildings. Earlier steel production was prohibitively expensive.
