The 'Talbot' name was given to car manufacture by an English Lord who went into business with Frenchman Clement-Bayard in 1903, producing English-sold 'Clement-Talbot' cars and French-sold 'Clement-Bayard' cars. The French business accepted a buyout from Andre Citroen in 1922 and the Clement-Bayard name was then lost. The Clement-Talbot business began to build its own designs from 1906, selling these as 'Talbots', but these became 'Talbot-Darracqs' after the Darracq buyout in 1919. In 1920 Sunbeam merged into this business to create Sunbeam-Talbot-Darracq (or 'STD'), a confusing mix of English and French companies. By 1935 STD were in decline, with only the Talbot brand successful in both sales and sports wins mainly due to their Swiss engineer Georges Roesch. William and Reginald Rootes bought Talbot out of STD in 1935, and started to use the chassis and mechanics of Hillman and Humbers as the basis of 'Talbot London' cars, giving them their own Talbot bodies.
