Edmund Cartwright

Born 24 Apr 1743; died 30 Oct 1823 at age 80.In 1784, Cartwright visited a factory owned by Richard Arkwright. Inspired by what he saw, he began working on a machine that would improve the speed and quality of weaving. With the help of a blacksmith and a carpenter, Cartwright produced his power loom, which he patented (1785). The invention revolutionised weaving, changing it from a manual process into a mechanical one. By 1787, he opened a weaving mill in Doncaster. Two years later, he powered his looms with steam engines produced by James Watt and Matthew Boulton. He also invented a machine for combing wool. In 1793 his business failed but parliament recognized his achievements in 1809 with an award of £10,000.
