Smith of Derby Group
Smith of Derby Group is a clockmaker based in Derby, England founded in 1856. Smith of Derby has been operated continuously under five generations of the Smith family. History 

John Smith (21 December 1813 - 1886) became an apprentice to John Whitehurst in 1827. He went on to be the founder of a new clockmaking company in 1856, first establishing his business in premises at 27 Queen Street in Derby. John Smith's new company flourished during the industrial revolution. When he died in 1886, his two sons, Frank and John took over the running of the family business. Under Frank Smith, the company were responsible for building the huge turret clock for St Paul's Cathedral in 1893. Frank Smith died in 1913, and the company was run by staff until his son Alan was old enough to take over the running of the business. Alan Smith was succeeded by Howard Smith, who in turn, was succeeded by Nicholas Smith. During the 20th century, Smith and Sons expanded through the acquisition of a variety of businesses. Clockmakers William Potts & Sons, Leeds were established in 1833 and acquired by Smith of Derby in 1933; JB Joyce & Co of Whitchurch were responsible for many clocks internationally and were acquired by Smith of Derby in 1965; George & Francis Cope were established in 1845 as producers of chronometers for the Admiralty, and joined Smith of Derby in 1984. In 1985 they acquired B & H (Derby) Ltd and became the current Smith of Derby Group. In 2013, the company acquired the historical Scottish clockmaker James Ritchie & Son but continue to operate the firm as a subsidiary. Public clock installations in Europe
