John Smedley (industrialist)
John Smedley is the name of four generations of owners of Lea Mills, near Matlock, Derbyshire. The most famous of these was John Smedley (1803-1874), born Wirksworth, Derbyshire.
Lea Mills was founded in 1784 by Peter Nightingale (a relation of Florence Nightingale) (former accountant to Richard Arkwright), 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.

John Smedley's son, also named John Smedley, was born on 12 June 1803.
In 1819 the younger John Smedley began work as an apprentice. In 1825 he took over the running of the mill, and started an energetic expansion of its operations. The mill at this time had already diversified from cotton to wool, and from simply weaving to knitting. Smedley the younger's plan was to produce a wide range of finished garments, rather than simply manufacture cloth.
In 1847 he married Caroline Harward, the second daughter of John Harward the Vicar of Wirksworth.
Smedley's success and growing wealth enabled other grand projects. He developed an interest in hydrotherapy, and built Smedley's Hydro in Matlock, a spa resort that attracted patrons from around the world. As a family home he also built the massive and ostentatious Riber Castle on a hilltop overlooking Matlock. This is now one of Derbyshire's most famous landmarks.
Smedley died on 27 July 1874, and upon his death the business passed to his cousin, John T Marsden Smedley, and thence to John B Marsden Smedley. In 1893 the operation became a limited company.
The designer label John Smedley is now familiar in boutiques, department stores and classic retailers around the world. The company sells to over 30 countries and has won numerous awards for its export achievements. The largest export market is Japan. There are concessions in some branches of Selfridges and Fenwick.
