Gustave Adolphe Clément, from 1909 Clément-Bayard (22 September 1855 – 10 March 1928), was a French entrepreneur. An orphan who became a blacksmith and a Compagnon du Tour de France, he went on to race and manufacture bicycles, pneumatic tyres, motorcycles, automobiles, aeroplanes and airships. In 1894 he was a passenger in the winning vehicle in the world's first competitive motor event. Albert Lemaître's Peugeot was judged to be the winner of the Paris–Rouen Competition for Horeseless Carriages (Concours des Voitures sans Chevaux).
