John Oldham (engineer) : ウィキペディア英語版 | John Oldham (engineer) John Oldham (1779–1840)〔(Biography of Oldham at Cornell University )〕 was an Irish engineer, now best known for the Oldham coupler. ==Life== Born in Dublin, Oldham was apprenticed to an engraver there, but then became a miniature-painter. He invented a numbering machine, which in 1809 he unsuccessfully offered to the bank of Newry for numbering their banknotes. In 1812 the machine was adopted by the Bank of Ireland, and he received the appointment of engineer and chief engraver. In 1837 Oldham entered the service of the Bank of England, where he introduced improvements in the machinery for printing and numbering banknotes. This machinery continued in use until 1852–3, when the system of surface-printing was adopted. He died at his house in Montagu Street, Russell Square, London, on 14 February 1840.〔
