For all of these, Martin collaborated with Bob Baker. Together they were nicknamed "The Bristol Boys" by the Doctor Who production teams with whom they worked.
Baker and Martin's most notable contributions to the Doctor Who mythos were the robotic hound K-9 (created for The Invisible Enemy) and the renegade Time Lord Omega (created for The Three Doctors, Doctor Who's tenth anniversary story).
They also worked together on the 1975 children's science fantasy television serial Sky and Into the Labyrinth.
In 1986, he wrote the Doctor Who Make Your Own Adventure book Search for the Doctor.
At the beginning of 2007 Martin, a smoker, was diagnosed with lung cancer; he died of the disease in March. He and his wife Celia (née Constanduros, born 1944), had two children, Leo and Thea; he also had a daughter, Anna, from his first marriage.
