Claremont's career began in 1969, as a college undergraduate, when he was hired as a gofer/editorial assistant at Marvel Comics. His first professional scripting assignment was "Daredevil" #102 (Aug. 1973). As an entry into regular comics writing, Claremont was given the fledgling feature "Iron Fist" in "Marvel Premiere" as of issue #23 (Aug. 1975). He was joined two issues later by artist John Byrne. The Claremont/Byrne team continued to work together when the character received its own self-titled series in November 1975 which lasted 15 issues.
