Architects' sources of inspiration are often surprising, but none more so than the trigger for the Rogers and Piano Pompidou Centre. Cedric Price's Fun Palace is often cited but, according to a recent radio programme, another portly, well-loved figure also played a key role. Discoursing on the charms of Rupert Bear, the presenter revealed that the check-trousered one was important to Rogers' vision of the Pompidou. 'Rupert cartoons can be read in a number of ways - you can look at the pictures, read the speech bubbles, read the verses or the longer explanations underneath, ' we heard. Rogers, it was said, was inspired by Rupert to adopt a similarly multivalent approach in Paris. Thank goodness the bear's trouser taste didn't prove equally influential (except on Sheffield school chief Jeremy Till).
