What author was still an English teacher at Maine's Hampden Academy when his first book was published?

Stephen Edwin King (born September 21, 1947) is an American author of horror, supernatural fiction, suspense, science fiction, and fantasy. His books have sold more than 350 million copies, many of which have been adapted into feature films, miniseries, television series, and comic books. King has published 54 novels, including seven under the pen name Richard Bachman, and six non-fiction books. He has written around 200 short stories, most of which have been collected in book collections.

King graduated from the University of Maine in 1970 with Bachelors of Arts in English. After leaving the university, King earned a certificate to teach high school but, unable to find a teaching post immediately, initially supplemented his laboring wage by selling short stories to men's magazines such as Cavalier. In 1971, King married Tabitha Spruce, a fellow student at the University of Maine whom he had met at the University's Fogler Library after one of Professor Hatlen's workshops. That fall, King was hired as a teacher at Hampden Academy in Hampden, Maine. He continued to contribute short stories to magazines. In 1973, King's first novel "Carrie" was accepted by publishing house Doubleday.

King has stated that he donates approximately $4 million per year "to libraries, local fire departments that need updated lifesaving equipment (Jaws of Life tools are always a popular request), schools, and a scattering of organisations that underwrite the arts."
