So who would you name as the greatest living architect? Meier, quite possibly. Foster, a worthy contender. I M Pei, maybe. Jean Nouvel, if you're young and trendy. Calatrava, if you don't have too many scruples about bending moments. Gehry, most certainly. Piano, perche non? And Steven Holl, for the intellectual. All these figured in a recent Architectural Record straw poll among us architects, but the winning line was: 'Wake up! Individual figures can't take sole credit any more!'
