Pseudonym

A number of Doctor Who Universe writers (and in some cases actors) have employed pseudonyms separate from the usual stage or pen names.

On television

 * Norman Ashby: A pseudonym employed by Mervyn Haisman and Henry Lincoln for The Dominators after they felt mistreated by the then-production team.
 * Robin Bland: Terrance Dicks, who felt dissatisfied with re-writes to his script for The Brain of Morbius by then-script editor Robert Holmes and so requested it air under a different name. Robert Holmes saw to it that the story came out as by "Robin Bland".
 * David Agnew: A shared pseudonym used on various BBC productions rather than just on Doctor Who. Credited for scripts to The Invasion of Time (actually by Graham Williams and Anthony Read) and for City of Death, Script Editor Douglas Adams' re-work of David Fisher's original script A Gamble With Time.
 * Paula Moore: A pseudonym used for the script to Attack of the Cybermen by Paula Woolsey, though both Eric Saward and Ian Levine have claimed credit for at least some of the writing. The alias "Mrs. Moore" in The Age of Steel refers to this.

In comics

 * Maxwell Stockbridge: This pseudonym (possibly referencing the fictional town of Stockbridge from early Doctor Who Monthly stories) concealed the identity of Doctor Who Magazine editor Alan McKenzie.
 * Richard Alan: A pseudonym used by Richard Starkings for co-writer credit on his Doctor Who Magazine comics stories.

Prose fiction

 * John Lydecker: A pseudonym used by Steve Gallagher for his Doctor Who-related prose work.
 * James Stevens: A fictional co-author (who narrates the book) used by actual author David Bishop in his Who Killed Kennedy.
 * David Agnew: A joking reference to previous "David Agnew" scripts used for some stories printed in Short Trips and Side Steps.
 * Tara Samms: An occasional pen name used by Stephen Cole for short fiction.
 * Norman Ashby: Another supposed contributor to Short Trips and Sidesteps.

Actors

 * Sydney Wilson: So as not to reveal the actual identity of Koquillion (in reality Bennett), the ending credits for the first episode of The Rescue, credited the actor as "Sydney Wilson", a name which combined the names of Sydney Newman and Donald Wilson.
 * Various: Radio Times listings would often credit Anthony Ainley under a pseudonym to conceal his appearances as the Master before those episodes had aired. Usually, the names took the form of anagrams of "the Master", though the listing for The King's Demons listed him as "James Stoker", an anagram for "the Master's joke".
 * Roy Tromelly: An anagram of the name of Terry Molloy used to conceal the true identity of the Emperor Dalek (in fact Davros) for most of the story.
