Creator of the characters Gandalf and Gollum (7)

Ross

I believe the answer is:

tolkien

(Other definitions for tolkien that I've seen before include "Oxford philologist and fantasy writer (1892-1973)" , "Middle Earth creator" , "professor of Anglo-Saxon" , "Writer of The Hobbit" , "Hobbit deviser" .)

I've seen this clue in The Sun.
