GKN plc is a British multinational automotive and aerospace components company headquartered in Redditch, Worcestershire. The company was formerly known as Guest, Keen and Nettlefolds and can trace its origins back to 1759 and the birth of the Industrial Revolution. GKN is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index. The origins of GKN lie in the founding of the Dowlais Ironworks in the village of Dowlais, Merthyr Tydfil, Wales, by Thomas Lewis and Isaac Wilkinson. John Guest was appointed manager of the works in 1767, having moved from Broseley. In 1786, John Guest was succeeded by his son, Thomas Guest, who formed the Dowlais Iron Company with his son-in-law William Taitt. Guest introduced many innovations and the works prospered.
