I don't know if he's mentioned already, but Roald Dahl seems quite the ENTP to me. I've reread "Boy" lately, where he tells some anecdotes from his childhood.
(I've recently aquired some more Roald Dahl goodness in English...)

What about Douglas Adams, by the way? That's pure Ne overkill. And it doesn't seem seasoned with values... There is a little hint of internal logic, though. But only a little.
