Biography of Sir Henry Bessemer


Bessemer, Sir Henry. Civil engineer and inventor. Born at Charlton, Herts., in 1813. Of his many inventions, the chief is the process named after him, of converting pig-iron into steel at once by blowing a blast of air through the iron while in fusion until everything extraneous is expelled and only a definite quantity of carbon is left in combination. This process revolutionized the iron and steel trade all over the world-leading, as has been calculated, to the production of thirty times as much steel as before, and at one-fifth the cost per ton. Died 1898.
