Lea Mills

Lea Mills was founded in 1784 by Peter Nightingale and John Smedley (father of the better-known son of the same name). It was set up on a hilly site straddling a brook at Lea Bridge, just outside Matlock. The brook was used to both clean yarn and power machinery. The mill specialised in the production of muslin and spinning cotton to send out to local cottages with hand frame looms. Towards the end of the 18th century, the company had extended its activities to include knitting and hosiery manufacture - said to be the origin of Long Johns. By this time, John Smedley was running the business alone, although the Nightingale family retained an interest in the property. As Lea Mills remains open and an operational building to this day, manufacturing the company's range of designer knitwear, John Smedley claims to be world's longest running factory manufacturer.
