J. K. Rowling

J.K. Rowling, real name Joanne Rowling (b. 1965), was the author of the very successful Harry Potter series of novels, publishing seven volumes between 1997 and 2007. Her books were also adapted as a successful series of movies.

The Doctor was a fan of the Potter books, and admitted to crying after reading the final volume, Harry Potter and the Deathly Hollows. Later, when Potter's spell "expelliarmus" is given life in order to help William Shakespeare defeat the carrionites, the Doctor exclaims, "Way to go, J.K.!" (DW: The Shakespeare Code)
