Sir Henry Bessemer (19 January 1813 15 March 1898) was an English engineer and inventor. Bessemer''s name is chiefly known in connection with the Bessemer process for the manufacture of steel. Henry Bessemer''s father, Anthony, was born in London, but moved to Paris when he was 21 years old. He was an inventor who while he was engaged by the Paris Mint, made a machine for making medallions that could produce steel dies from a larger model. He became a member of the French Academy of Science, for his improvements to the optical microscope, when he was only 26. He was forced to leave Paris by the French Revolution of 1848, and returned to Britain. There he invented a process for making gold chains, which was successful, and enabled him to buy a small estate in the village of Charlton, near Hitchin in Hertfordshire, where Henry was born in 1813.
