Who invented the steel process?

Who invented the steel process?

• A. Henry Bessemer
• B. Andrew Carnegie
• C. Cornelius Vanderbilt
• D. JP Morgan

Answer: (A)

Mass production of steel in the 19th century hinged on a method that could remove impurities from pig iron by blowing air through it, making steel cheaper and stronger for widespread use. This process was invented by Henry Bessemer in 1856, and it became the key technique that enabled the rapid expansion of the steel industry. Andrew Carnegie later built a huge steel empire in the United States by adopting and scaling the Bessemer process, but he did not invent it. Cornelius Vanderbilt and JP Morgan were influential in railroads and finance, not in creating the steel-making method itself.
