Cromford is a community in Derbyshire, three kilometers south of Matlock on the Derwent River, of great industrial importance as it is the cradle of the Industrial Revolution. Richard Arkwright established the world's first cotton factory here in 1771, using the water-powered Waterframe he developed to revolutionize cotton spinning. The factory is today part of the World Heritage Derwent Valley Mills as Masson Mill. A district of the Rhenish town of Ratingen, where the Cromford textile factory was founded 10 years later by the Cromford textile factory, based on the Arkwrights factory, is still named after Cromford.
