J.R.R. Tolkien vs. the Nazis.

From Letters of Note:

I have been accustomed, nonetheless, to regard my German name with pride, and continued to do so throughout the period of the late regrettable war, in which I served in the English army. I cannot, however, forbear to comment that if impertinent and irrelevant inquiries of this sort are to become the rule in matters of literature, then the time is not far distant when a German name will no longer be a source of pride.
