ROEBUCK, See also:JOHN (1718-1794) , See also:English inventor, was See also:born in 1718 at See also:Sheffield, where his See also:father had a prosperous manufacturing business. After attending the See also:grammar school at Sheffield and Dr See also:Philip See also:Doddridge's See also:academy at See also:Northampton, he studied See also:medicine at See also:Edinburgh, where he was imbued with a See also:taste for See also:chemistry by the lectures of See also:William See also:Cullen and See also:Joseph See also:Black, and he finally graduated M.D. at See also:Leiden in 1742. He started practice at See also:Birmingham, but devoted much of his See also:time to chemistry, especially in its See also:practical applications. Among the most important of his See also:early achievements in this See also:field was the introduction, in 1746, of leaden condensing See also:chambers for use in the manufacture of sulphuric See also:acid. Together with See also:Samuel Garbett he erected a factory at See also:Prestonpans, near,Edinburgh, for the See also:production of the acid in 1749, and for some years enjoyed a See also:monopoly; but ultimately his methods became known, and, having omitted to take out See also:patents for them at the proper time, he 'was unable to restrain others from making use of them. Engaging next in the manufacture of See also:iron, he in 176o established the ironworks which still exist at Carron, in See also:Stirlingshire. There he introduced various improvements in the methods of production, including the See also:conversion (patented in 1762) of See also:cast iron into malleable iron " by the See also:action of a hollow See also:pit-See also:coal See also:fire " urged by a powerful artificial blast. His next enterprise was less successful. He leased a colliery at Bo'ness to See also:supply coal to the Carron See also:works, but in sinking for new seams encountered such quantities of See also:water that the See also:Newcomen See also:engine which he used was unable to keep the pit clear. In this difficulty he heard of See also:James See also:Watt's engine and entered into communication with its inventor. This engine, then at an early See also:stage of its development, also proved in-adequate, but Roebuck became a strong believer in its future and in return for a two-thirds See also:share in the invention assisted Watt in perfecting its details. His troubles at the colliery, however, aggravated by the failure of an See also:attempt to manufacture See also:alkali, brought him into pecuniary straits, and he parted with his share in Watt's engine to See also:Matthew See also:Boulton in return for the cancellation of a See also:debt of £1200 which he owed the latter.

Subsequently, though he had to give up his See also:

interest in the Bo'ness works, he continued to See also:manage them and to reside at the neighbouring Kinneil See also:House, where he occupied himself with farming on a considerable See also:scale. He died on the 17th of See also:July 1794.
