Quarry Bank Mill in Styal, Cheshire, England, is one of the best preserved textile factories of the Industrial Revolution. Built in 1784, the cotton mill is recorded in the National Heritage List for England as a designated Grade II* listed building. Quarry Bank Mill was established by Samuel Greg, and was notable for innovations both in machinery and also in its approach to labour relations, the latter largely as a result of the work of Greg's wife, Hannah Lightbody. The family took a somewhat paternalistic attitude toward the workers, providing medical care for all and limited education to the children, but all laboured roughly 72 hours per week until 1847 when a new law shortened the hours.
