In 1963, he set up the Design Department of the École nationale supérieure des arts décoratifs in Paris.
In 1974, with Jean-Charles de Castelbajac, he created a concept aircraft cabin for Air France.
[1] Tallon and his team created hundreds of products, including industrial robots for Peugeot, the apparently purposeless 8mm film camera "Veronic", the Gallic 16 and 14 lathes for the Belgian company La Mondiale – a quantum leap in machine tooling –, airport vehicles, forklifts for Fenwick, graphic images for Fenwick Aviation, and a slide projector for Kodak.
Tallon became a household name[citation needed] in areas including tableware, furniture, interior design, reflector lamps for the German Erco, watches for Lip, ski boots for Salomon Group, toothbrushes for Fluocaril, oilcans for Elf, and so on.
In the transport world, an early Tallon design was the Derny 'Taon' motorcycle and he later took on the Mexico City Metro and, for Alstom and the SNCF, the TGV and the locomotive for the Corail train.
