For particular interest is this FTA:

The publishers of the German translation of The Hobbit wanted Tolkien to affirm he was “of Aryan origin” before they would issue the work in 1938. Tolkien wrote an agitated reply to his British publishers complaining of the “lunatic laws” of the Third Reich, saying (Letters, pp. 37-38):

Personally I should be inclined to refuse to give any Bestätigung [confirmation] (although it happens that I can), and let a German translation go hang. In any case I should object strongly to any such declaration appearing in print. I do not regard the (probable) absence of all Jewish blood as necessarily honourable; and I have many Jewish friends, and should regret giving any colour to the notion that I subscribed to the wholly pernicious and unscientific race-doctrine.

In the draft of the letter to the German publisher, he declared:

I regret that I am not clear as to what you intend by arisch. I am not of Aryan extraction: that is Indo-iranian; as far as I am aware none of my ancestors spoke Flindustani, Persian, Gypsy, or any related dialects. But if I am to understand that you are enquiring whether I am of Jewish origin, I can only reply that I regret that I appear to have no ancestors of that gifted people….

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.
