Harlan Ellison, born in 1934, was a prolific writer known for his work in "New Wave" speculative fiction. He published over 1,700 short stories, screenplays, teleplays and novels/novellas. While in the U.S. Army he wrote and published his first novel "Web of the City" in 1958. After his military service he worked for a time as an editor at "Rogue" Magazine in Chicago. In 1962 he moved to Los Angeles and began selling scripts to Hollywood. Among his work in television, he wrote for TV shows such as "The Outer Limits", "The Man from U.N.C.L.E." and "Star Trek".

His "Star Trek" story "The City on the Edge of Forever" was aired in 1967 during the show's first season. There were several writers who contributed to the finished show, with a final rewrite by "Star Trek" creator and producer Gene Roddenberry. In this episode the crew of the Enterprise is investigating an unknown time phenomenon, a heavily drugged Dr. McCoy (played by DeForest Kelley) travels back in time to 1930s America and alters history.
