Thomas Cotchett, an attorney and owner of a silk-throwing mill
1702 Thomas Cotchett set up a mill at Derby for twisting silk using water power (up to that time silk twisting had been done by hand in Britain although such mills had been in use in Italy since 1272). The water wheel, 13.5 feet in diameter, was built by local engineer George Sorocold. It was used to drive machinery probably of Dutch origin. The silk thread would probably have been used to make organzine.
Died in or after 1713
