Born on 26 July 1939, Baker was a Doctor Who writer who often wrote alongside his late writing partner Dave Martin. Baker and Martin are best remembered for creating K9, the Doctor’s robot dog. K9 first appeared in the Season 15 story The Invisible Enemy.

Baker partially owned the rights to K9. He made use of these rights in authorising the creation of the K9 TV series.

Baker’s greatest success after Doctor Who was as a writer for Aardman Animations’ Wallace and Gromit series.

Baker also co-wrote the short films The Wrong Trousers, A Close Shave with animator Nick Park. He also co-wrote A Matter of Loaf and Death the feature film Wallace & Gromit: The Curse of the Were-Rabbit; both for which he received a BAFTA.

Baker had recently completed scripts for a new K9 film and TV Series, which will continue in tribute to him.

A prolific film and television writer with a rich and varied life, Baker is survived by his wife Marie, two sons, six daughters and seven grandchildren.
