Martin attended Mary Jane Donohoe School and Marist High School. He began writing very young, selling monster stories to other neighborhood children for pennies, dramatic readings included. Later he became a comic book fan and collector in high school, and began to write fiction for comic fanzines (amateur fan magazines). Martin's first professional sale was made in 1970 at age 21: "The Hero," sold to Galaxy, published in February, 1971 issue. Other sales followed.
