Gillett & Johnston

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.
