Gillett & Johnston was a clockmaker and bell foundry based in Croydon, England from 1844 until 1957. Between 1844 and 1950, over 14,000 tower clocks were made at the works. The company's most successful and prominent period of activity as a bellfounder was in the 1920s and 1930s, when it was responsible for supplying many important bells and carillons for sites across Britain and around the world. A successor company continues operation in Bletchingley, Surrey, under the Gillett & Johnston name, engaged in clock-making and clock and carillon repair. History The company traced its roots to a clockmaking business established by William Gillett in Hadlow, Kent, in the early 19th century. In 1837, Gillett moved his business to Clerkenwell, London; and in 1844 to the site in what later became known as Union Road, Thornton Heath, Croydon, which would remain its home for the next 113 years. Charles Bland became a partner in 1854, and the company subsequently traded as Gillett & Bland. In 1877, Arthur A. Johnston (c.1851–1916) bought a partnership, and shortly afterwards extended the company's output by establishing a bell foundry. The business became known as Gillett, Bland & Co until Bland's death in c.1884, when the name was changed to Gillett & Co. The name Gillett & Johnston seems to have been used from around 1887. Arthur Johnston's son, Cyril Frederick Johnston (1884–1950), joined the company in 1902, became a partner in 1907, and took over the firm following his father's death in 1916. He developed an interest in the theory of bell-tuning, and greatly expanded the bellfounding side of the business. In 1905 he redeveloped the works, and installed a large vertical tuning lathe. He was particularly interested in the manufacture of carillons, which presented special problems of tuning distinct from those of church bells. During the First World War, the factory suspended its regular business and became involved in the manufacture of munitions, employing over 1,250 men and women. The firm became a limited liability company in 1925, initially trading as the Croydon Bell Foundry Ltd (although the name "Gillett and Johnston" still appeared on bells). It reverted to the name Gillett & Johnston Ltd in 1930. Cyril Johnston resigned as managing director in 1948, following disagreements over company policy, and died suddenly two years later in 1950. Following his departure, Henry Michael Howard took over, and some bells were cast in his name.
