'I hardly think that he could be called a "genius " !! '

Maybe not, but what he has achieved is more crediatble in my eyes that many people who are called a genius.

I heard Ann Widdecombe described as 'a bit of a genius' just recently.

Fleming, Brunel, Frank Whittle (no relation), Mozart, Einstein, Shakespeare.... I suppose we can all agree on the obvious ones. But you don't get far down the list before it becomes debatable. I met a jazz trumpeter last month who didn't reckon much of Bix Beiderbecke.
