Answer: Stephen King

While working on his 1980 novel Fire-Starter, Stephen King found himself with a protagonist in want of a technical term to describe her ability to create fire with her mind. Taking a cue from an earlier writer, Henry Holt, King modified Holt’s early 20th-century coinage of Psychokinesis into Pyrokinesis. After appearing in the novel the term entered popular usage and has made appearances in many comic books, televisions shows, and movies, including The X-Files, The X-Men, and The Dresden Files.
