A Literary Parallel

It is getting late here and I can't find all the references right now but let me first describe a fictional character, then ask a question, then maybe turn in for the night.

John Gardner's Big Herbie Kruger

Competent, effective and professionally successful.

Deliberately gives the opposite impression.

Unconventional.

A law unto himself.

German.

Speaks English as if not quite fluent.

Communicates in puns and malapropisms.

But can speak English correctly when necessary.

Question

Which Poul Anderson character does this sound like?

Comment

Pretty obvious.

Good Night.

Good night.
