Sir William Congreve

Born 20 May 1772; died 16 May 1828 at age 55. English artillery officer and inventor (2nd Baronet) who invented a rocket (about 1804) for use in warfare that improved on simple black-powder rockets. They were first used militarily against the French on 8 Oct 1806 at Boulogne and later at Copenhagen and Leipzig. By 1830, most European armies had copied them. He also invented a gun-recoil mounting, a steam engine, a triple-paper process for coloured watermarks and a “perpetual-motion” machine. He created a wheelchair for himself after losing the use of his legs. He designed a vessel propelled by a “wave-wheel” and a human-powered aircraft. His 18 patents also include making of gunpowder, gas lighting, “hydropneumatic” canal locks, a rolling-ball clock and a built-in sprinkler system.«
