Before joining the army he took part in a model-making competition organized by L'Auto, taking first prize for a model subsequently manufactured for sale in Parisian department stores.
Demobilised in 1902, Béchereau joined a mechanical construction factory in Bezons where he took part in the development of a prototype car designed by Clément Ader.
In 1909 a client of the firm, Armand Deperdussin, had ordered the construction of an aeroplane that was exhibited in the windows of the Bon Marché store in Paris.
During the First World War, when Georges Guynemer received his first SPAD S.VII equipped with a Hispano-Suiza engine on 27 August 1916, he wrote to Louis Béchereau the next day praising the wonders of this new aeroplane.
[citation needed] It was Guynemer who later presented Béchereau with the medal of the Chevalier of the Légion d'honneur on 12 July 1917 in the SPAD works, in the presence of the Minister of War.
