Cort, Henry

born 1740, Lancaster, Lancashire, Eng.
died 1800, London

British inventor and industrialist.

In 1783 he obtained a patent for producing iron bars quickly and economically in a rolling mill with grooved rolls. The following year he patented his puddling process for converting pig iron into wrought iron in a reverberatory furnace. His two inventions had a significant effect on Britain's iron-making industry, and iron production quadrupled in the next 20 years.

      British discoverer of the puddling process for converting pig iron into wrought iron.

      Having accumulated capital by serving 10 years as a civilian official of the Royal Navy, Cort bought an ironworks near Portsmouth in 1775. In 1783 he obtained a patent for grooved rollers that were capable of producing iron bars more quickly and economically than the old methods of hammering or of cutting strips from a rolled plate. The following year he patented his puddling process, which consisted of stirring molten pig iron on the bed of a reverberatory furnace (one in which the flames and hot gases swirling above the metal provide the heat, so that the metal does not come in contact with the fuel). The circulating air removed carbon from the iron. Exactly how Cort's process differed from the processes that had been developed by earlier ironmasters along the same lines is not known, but his two inventions together had a tremendous effect on the iron-making industry in Britain; in the next 20 years British iron production quadrupled.

      The discovery that his partner had invested stolen funds in the enterprise led to Cort's being deprived of his patents and forced into bankruptcy, though he was eventually granted a modest pension.
