Lewis Greifer
From Tardis Wiki, the free Doctor Who reference
Lewis Greifer (19 December 1915-18 March 2003[1]) wrote the original script for the Doctor Who television story Pyramids of Mars. However, since it was considered unworkable and Greifer was unavailable, it was rewritten by Robert Holmes, under the pseudonym of Stephen Harris, leaving little to nothing of Griefer's original story.
