The Great BBC Fridge Magnet Challenge

Jon Manel, BBC Radio 4's 'man at the pitchside' at the World Cup, laid down a challenge to his listeners to tell him 'Who invented the fridge magnet?'

Without a definitive response, Jon's gauntlet still lies on the floor.

There's a free magnet available for anyone who can supply the answer.

(Jon's diary - which references fridge magnets throughout! - can be found here.)

And don't you go rushing off to Wikipedia for the answer - the boys at Wiki don't know!
