sandyRoe,
Not Gustave Flaubert either, though a close likeness I will admit.
Just google Fibonacci's clue and you should find him without too much effort. It's a shame to just give the name I always think.
Good Luck.
Fibonacci,
Returning the favour - one of the most famous names in the haulage business, but none of his lorries are named after him!
But be careful you get the right generation.
