    SUBJECT AREA: Metallurgy
    [br]
    b. 1740 Lancaster, England
    d. 1800 Hampstead, near London, England
    [br]
    English ironmaster, inventor of the puddling process and grooved rollers for forming iron into bars.
    [br]
    His father was a mason and brickmaker but, anxious to improve himself, Cort set up in London in 1765 as a navy agent, said to have been a profitable business. He recognized that, at that time, the conversion of pig iron to malleable or wrought iron, which was needed in increasing quantities as developments in industry and mechanical engineering gathered pace, presented a bottleneck in the ironmaking process. The finery hearth was still in use, slow and inefficient and requiring the scarce charcoal as fuel. To tackle this problem, Cort gave up his business and acquired a furnace and slitting mill at Fontley, near Fareham in Hampshire. In 1784 he patented his puddling process, by which molten pig iron on the bed of a reverberatory furnace was stirred with an iron bar and, by the action of the flame and the oxygen in the air, the carbon in the pig iron was oxidized, leaving nearly pure iron, which could be forged to remove slag. In this type of furnace, the fuel and the molten iron were separated, so that the cheaper coal could be used as fuel. It was the stirring action with the iron bar that gave the name "puddling" to the process. Others had realized the problem and reached a similar solution, notably the brothers Thomas and George Cranage, but only Cort succeeded in developing a commercially viable process. The laborious hammering of the ball of iron thus produced was much reduced by an invention of the previous year, 1783. This too was patented. The iron was passed between grooved rollers to form it into bars. Cort entered into an agreement with Samuel Jellico to set up an ironworks at Gosport to exploit his inventions. Samuel's father Adam, Deputy Paymaster of the Navy, advanced capital for this venture, Cort having expended much of his own resources in the experimental work that preceded his inventions. However, it transpired that Jellico senior had, unknown to Cort, used public money to advance the capital; the Admiralty acted to recover the money and Cort lost heavily, including the benefits from his patents. Rival ironmasters were quick to pillage the patents. In 1790, and again the following year, Cort offered unsuccessfully to work for the military. Finally, in 1794, at the instigation of the Prime Minister, William Pitt the Younger, Cort was paid a pension of £200 per year in recognition of the value of his improvements in the technology of ironmaking, although this was reduced by deductions to £160. After his death, the pension to his widow was halved, while some of his children received a pittance. Without the advances made by Cort, however, the iron trade could not have met the rapidly increasing demand for iron during the industrial revolution.
