Engineering achievements

John Rennie's work on canals, aqueducts, bridges and dockyards mark him as one of the greatest engineers of his age.

Rennie was born near East Linton, 20 miles east of Edinburgh. He played truant from school to watch Andrew Meikle, the local millwright and inventor of the threshing machine, and began to work there when he was 12, while continuing his education. He studied at Edinburgh University and then worked for Matthew Boulton and James Watt , manufacturer of steam engines.

When he was 29, he moved to London and set up his own engineering business. His first works were the Lancaster Canal, the Kennet & Avon Canal, the Royal Military Canal, and improving the drainage of the Norfolk fens. He also designed bridges in stone and cast iron with daringly wide arches - like Kelso Bridge, Waterloo Bridge, Southwark Bridge and London Bridge, completed by his son George after his death. His docks and harbours included Grimsby, Leith and the London Docks. But his largest projects were for the Royal Navy as it built the infrastructure for its century of world domination, including Sheerness Dockyard and the great breakwater at Plymouth. Rennie also gave advice on novel maritime structures such as steam-powered dredgers, diving bells and the Bell Rock lighthouse.
