George Rennie (engineer)

George Rennie (3 December 1791 – 30 March 1866) was an engineer born in London, England. He was the son of the Scottish engineer John Rennie and the brother of Sir John Rennie.

Born in the parish of Christchurch, Blackfriars Road, Southwark, London, on 3 December 1791, he was educated by Dr. Greenlaw at Isleworth, and was subsequently sent to St. Paul's School and to the University of Edinburgh. In 1811 he entered his father's office, where many great works were in progress. In 1818, on the recommendation of Sir Joseph Banks and James Watt, he was appointed inspector of machinery and clerk of the irons (i.e. dies) at the Royal Mint, which post he held for nearly eight years.

On the death of his father in 1821 he entered into partnership with his younger brother John, as J. and G. Rennie, and for many years they were engaged in completing the vast undertakings originated by the elder Rennie. John concentrated on the civil engineering portion of the business, whereas George supervised the mechanical engineering. Nevertheless, about 1826 he was entrusted with the construction of the Grosvenor Bridge (Chester) over the Dee at Chester, from the designs of Harrison.

In 1830, they were involved in the construction of George Stephenson's Liverpool and Manchester Railway. He had considerable practice as a railway engineer, and made plans for lines to connect Birmingham and Liverpool, the Vale of Clwyd line, the railway from Mons to Manage, and the Namur and Liege railway, of which he was appointed chief engineer in 1846.
