From the start of the 1950s, unlike most of his contemporaries, Roger Tallon (1929-2011) embarked on a path of industrial design. His career then lasted for fifty years in three agencies: Technès, Design Programmes and A.D.S.A. He advocated for global design in all fields: from the machine-tool to tableware, via signage and above all, from the 1970s, public transport. In this domain, his work with the SNCF is especially noteworthy. In 2008, he donated his entire archive to the MAD, that helped us having a comprehensive overview of his work: mainly industrial design, but also artistic experiments and teaching.
