help Henry Bessemer FAQ
What did Henry Bessemer invent?
Henry Bessemer was an English engineer who invented the Bessemer process in 1856. This was the first inexpensive industrial process for the mass production of steel from molten pig iron.
How does the Bessemer process work?
The process works by blowing air directly through molten pig iron to remove impurities like carbon and silicon. This oxidation process causes the iron to heat up and become decarburized, resulting in strong, workable steel.
Did Henry Bessemer have any competitors?
Yes, American inventor William Kelly independently discovered a similar air-blowing process around the same time. However, Bessemer's patented process became the globally dominant standard, leading him to eventually buy out Kelly's patents.
What impact did Bessemer's invention have on the world?
His process dramatically lowered the cost of steel production, making it affordable for widespread use in railroads, bridges, and skyscrapers. This material revolution was a major driving force behind the Industrial Revolution.
