J. K. Rowling

J.K. Rowling, also known as Joanne Rowling, is the author of the Harry Potter series of novels. In 2004, she was among the VIP guests for the gala opening of the Tomorrow Windows exhibit at the Tate Modern. (EDA: The Tomorrow Windows)

The Tenth Doctor and Martha Jones were fans of the Potter books, and the Doctor admitted to crying after reading the seventh volume. Later, when Potter's spell "expelliarmus" was given life in order to help William Shakespeare defeat the Carrionites, the Doctor exclaimed, "Good old J.K.!" (DW: The Shakespeare Code)

There is a possibly apocryphal account suggesting Rowling (or a successor) wrote as many as four more Harry Potter novels, which were later obtained by the Eighth Doctor. (EDA: The Gallifrey Chronicles) If a true account, then it's unclear to which book the Doctor was actually referring to in his discussion with Martha.

Behind the scenes

 * In The Tomorrow Windows her name is given as Joanne Rowling, the name used on the first publishing of the first Harry Potter book. In 2004, when The Tomorrow Windows was written and set, her married name was Joanne Murray and her pen-name was J.K. Rowling.
 * In 2005 Russell T Davies asked Rowling to write for Doctor Who, she said she was "was amused by the suggestion but simply [didn't] have the time". She was writing the sixth Harry Potter novel at the time.


 * In his 2008 autobiography, A Writer's Tale, Davies reveals that he considered basing the 2008 Christmas special around a guest appearance by Rowling.


 * The reference in The Gallifrey Chronicles to there being eleven Harry Potter novels can be seen as an anachronism (written in 2005, two years before the publication of Harry Potter and the Deathly Hallows, the author may have been unaware Rowling only planned seven books). However, Rowling has herself made comments since the publication of The Deathly Hallows that she hasn't dismissed the possibility of writing another Potter novel in the future; perhaps in the Who universe she did. The reference to the last book in The Shakespeare Code may settle the issue, as the Doctor referred to it by mentioning Book seven, which is actually the last one.
