Stephen Wiltshire can look at a target once and then draw a very accurate and very detailed picture of it. He once drew the whole of central London after a helicopter trip above it. Since 2004 he has drawn Berlin, Tokyo, Hong Kong, Rome and Frankfurt on giant panoramic canvasses entirely from memory.
Stephen is the only artistic autistic savant in the world whose work has been recorded and published since his childhood. His third book - Floating Cities (Michael Joseph, 1991) - was number one on the Sunday Times bestseller list.
