Brian Michael Stableford was a British academic, critic and science fiction writer who published more than 70 novels and over a hundred volumes of translations. His earlier books were published under the name Brian M. Stableford, but later ones dropped the middle initial and appeared under the name Brian Stableford. He also used the pseudonym Brian Craig for some of his very early and late works. The pseudonym derives from the first names of himself and of a school friend from the 1960s, Craig A. Mackintosh, with whom he jointly published some very early work.
