Smiths Group plc is a British, multinational, diversified engineering business headquartered in London, England. It operates in over 50 countries and employs 15,000 staff. Smiths Group is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
Smiths Group has its origins in a jewellery shop, S Smith & Sons, which was founded by the watchmaker and businessman Samuel Smith. Supplying its precision watches to various clients, including the Admiralty, the business quickly grew and expanded into a major provider of timepieces, diamonds, and automotive instrumentation. On 21 July 1914, the business became a public limited company, holding onto this status for over a hundred years. Significant restructuring of Smiths Group took place during the 1950s, the foundations of Smiths Medical Systems division were laid while Smiths Aviation and Smiths Marine were organised as separate divisions. Throughout much of the twentieth century, Smiths Group was the principal supplier of instruments to the British motorcar and motorcycle industries, organising itself as Smiths Industries Ltd in 1960.
By the late 1970s, the markets for clocks, watches, and automotive instruments had progressively decreased to the point where little of Smith's revenue came from these sources; Smiths Industries decided to cease its involvement as a direct supplier of Europe's automotive industry in the early 1980s. The medical division of Smiths Group was acquired by ICU Medical in January 2022. In 2026, Smiths Interconnect was sold to Molex, and Smiths Detection was sold to CVC Capital Partners. Following the sale of Smiths Interconnect and Smiths Detection, the business' operations are now primarily in industrial technologies. Its John Crane division focuses on rotating equipment, while Flex‑Tek focusses on engineered components.
