The Ripley area has been industrialised since the late 18th century. One of the earliest firms to take advantage of local mineral resources was the Butterley Company. It was formed in 1790 by Benjamin Outram and Francis Beresford. Jessop and Wright joined as partners in 1791. Benjamin Outram and Jessop were pioneering engineers best known for their input into the rail industry and their engineering of the Cromford Canal. Outram developed the L-shaped flange rail and Jessop engineered the cast iron fish belly rail. The Little Eaton Gangway project was one of the engineering feats they completed. The engineering part of the company closed and the site of the Butterley Company was demolished in 2010. The company was latterly in three parts, Butterley Engineering, Butterley Brick and Butterley Aggregates (all separate companies). Over the last 200 years these have dealt with steelworks, coal mining, quarrying, railway, foundry and brickworks. One of the best-known examples of the company's work is the arched roof of St Pancras railway station in London, recently restored as an international rail terminal. Recent major Butterley achievements were the design and construction of the Falkirk Wheel, a canal boat-lift funded by the Millennium Commission and the Spinnaker Tower seen in Portsmouth Harbour as the focus of its regeneration.
