they invented the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventors, who took out a patent on the process in 1855. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.
