Henry CortHenry Cort (1740 – 1800) was an English ironmaster. During the Industrial Revolution in England, Cort began refining iron from pig iron to wrought iron using innovative production systems. Born in Lancaster in 1740, his father was a builder. As a young man, he worked as a Royal Navy agent in London, where his interest in the poor quality of English iron against overseas supplies developed, leading to his inventions that greatly increased the quality of iron production. He left his job as an agent in 1775 and set up an iron works in Fontley, Hampshire, where he developed his ideas, leading to patents in 1783 for the steam-powered rolling process and 1784 for his balling or pudding furnace, allowing the manufacture of crude, standardized shapes. His work built on the existing ideas of the Cranege brothers and their reverberatory furnace (where the heat is applied from above, rather than forced air from below) and Peter Onions' puddling process where the iron is stirred to separate out impurities and extract the higher quality wrought iron. The "puddler" extracts a mass of iron from the furnace using a rabbling bar. The extracted ball of metal is then processed into a shingle by a shingling hammer, after which it is rolled. His partnership in the Fontley Mill was with Samuel Jellicoe (son of Adam Jellicoe, who had important Navy connections). This eventually turned out very badly, but initially the elder Jellicoe financed Cort's experimentation with large sums and a wharf at Gosport was purchased. On Adam Jellicoe's death (1789), he was in debt himself, and Cort's debts (guaranteed by his patents) to Jellicoe were called in to settle the estate. Because of the nature of the business, which was now vital to the supply of iron to the Navy, the patents were taken over by the Government. The younger Jellicoe was given sole control of the mill and wharf. Royalties on the patents were not recovered (which might have cleared Cort's debts) and so Cort's impoverishment was settled. He married and had a large family, but his business ventures did not bring him wealth, even though vast numbers of the furnaces that he developed were eventually used (reportedly 8,200 by 1820). He was awarded a government pension after leaving his firm, but died a ruined man, and was buried in Hampstead churchyard. External links Cort, Henry Cort, Henry
