Gil Kane (born Eli Katz, Latvian: Elija Kacs; April 6, 1926, January 31, 2000) was an American comics artist whose career spanned the 1940s to the 1990s and virtually every major comics company and character. Kane co-created the modern-day versions of the superheroes Green Lantern and the Atom for DC Comics, and co-created Iron Fist and Adam Warlock with Roy Thomas for Marvel Comics. He was involved in the anti-drug storyline in The Amazing Spider-Man #96 to 98, which, at the behest of the U.S. Department of Health, Education, and Welfare, bucked the then-prevalent Comics Code Authority to depict drug abuse, and ultimately spurred an update of the Code.
