Stevyn Colgan is an author, artist, public speaker and oddly-spelled Cornishman.
He has, among other things, been a chef, a brewer, a milkman, a comics publisher and the official artist for the 2006 UK National Children's Book Fair. He's written briefing notes for two prime ministers and TV scripts for Gerry Anderson, and he's helped build dinosaur skeletons for the Natural History Museum and movie monsters for Bruce Willis to shoot at.
But for thirty years he was a police officer in London, during which time he was set on fire twice, was sworn at by a royal, met two US presidents and a pope, was kissed by Princess Diana and let Freddie Mercury wear his helmet. In between such events he was part of the Met Police's experimental Problem Solving Unit.
He is a consultant for change agency Left/Field London and he is also one of the elves who research and write the popular BBC TV series QI and its sister show, The Museum of Curiosity, for BBC Radio 4.
