Jonathan Blum (born May 1972) is an American writer most known for his work for various Doctor Who spin-offs, usually with his wife Kate Orman although he has also been published on his own.
(He had contributed scenes to a couple of those books, Return of the Living Dad and The Room with No Doors, and been credited internally but not on the cover.)
He has also written the novella Fallen Gods, published by Telos Publishing Ltd. in 2003, which was highly popular and won the Aurealis Award for Best Australian Science Fiction Novel in 2003: the novella is credited to both Blum and Orman, but both authors have acknowledged that Blum did the majority of the writing and Orman's input was limited.
Blum has also written and directed a number of short films, including Audition For Murder, a tribute to the Australian adventure-spoof series Danger 5 which was approved by the show's producers.
In 2003 and 2005, he edited two no-budget, Doctor Who "inspired" indie shorts for Australian fan Andrew Merkelbach, The Curse of the Del Garria and Red.
