Sir Keith Gold was the director of the Inferno Project. He was concerned about Professor Stahlman's obsession with completing the project quickly, and called in Greg Sutton for advice on safety issues. He later went to the Ministry to recommend an inquiry into the project, but Stahlman had ordered his chauffeur Patterson to delay the return trip. Gold figured out what Patterson was doing and had him get back on the route to the project, but the car crashed soon afterwards. Sir Keith suffered only minor injuries and shut down the project.

Sir Keith had a counterpart in the parallel universe who was never actually seen, only mentioned. According to Director Stahlman, the alternate Sir Keith was killed in a car crash twenty-four hours previously. (TV: Inferno)
Gold resigned his post with the Ministry of Science soon afterwards. (PROSE: Who Killed Kennedy)
