Famous French industrial designer, Roger Tallon recently died, leaving something of a design mystery. Newspapers universally credited him as the designer of the iconic French high speed train, the TGV, but that was almost certainly the work of Jacques Cooper. Tallon did take over from Cooper to do the TGV Atlantique, but this was an evolutionary rather than a revolutionary design. Perhaps Tallon's influence was more on the interiors? For me, Tallon's best work was his 1960's M400 spiral stair which seems to be the direct inspiration for some of Ross Lovegrove's best work.
