What is it about Yorkshire, particularly Leeds, that it has bred or trained such a succession of famous modern sculptors? Moore, Hepworth, Armitage and, although it stretches the point, Hirst. All attended Leeds art schools and Armitage was born there on 18 July 1916. Everyone knows Moore, Hepworth, Hirst. But Armitage? How many under 60 remember him? Conventional opinion confines his relevance to the 1950s.
