John Campbell as a “non-writer”? What about “Who Goes There?”? “Forgetfulness”? “Cloak of Aesir”? And what about his monthly editorials?
I can see counting them as non-fiction, but surely they still count as writing?

And I wish whoever linked Campbell’s name to a webpage had found a more accurate one, one that would credit him with writing “Who Goes There?” rather than with “The Thing from Another World.” The Wikipedia article isn’t bad.
