On my way to Günther Uecker's (b. 1930) studio in Düsseldorf, I manage to lose my way, and when I ask for directions a helpful passerby points past a twisting trio of Frank Gehry buildings and says, 'Take a right at Uecker Platz.' Günther Uecker may have the honour of having a whole square christened after him, but he's not a grand figure. When I finally get to the studio, the artist himself greets me at the door of his huge, two-storey converted warehouse on the banks of the Rhine. (Uecker has been based here since 1987, when he moved out of the space he used to share with Gerhard Richter.)
