Gil Kane was a Latvian-born 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 with Roy Thomas for Marvel Comics. He was involved in such major storylines as that of The Amazing Spider-Man #96–98, 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. Kane additionally pioneered an early graphic novel prototype, His Name Is... Savage, in 1968, and a seminal graphic novel, Blackmark, in 1971. In 1997, he was inducted into both the Will Eisner Comic Book Hall of Fame and the Harvey Award Jack Kirby Hall of Fame.
In the 1950s, he worked for companies like Harvey, Toby Press, Charlton and Ziff Davis, doing western, horror and romance titles. He also did syndicated strips like 'Mister Rubbles' and 'Sam Hill'. For Gilberton's Classics Illustrated, Sparling drew 'Robin Hood' and Mark Twain's 'A Connecticut Yankee in King Arthur's Court'. In the late 1960s, Sparling was additionally present in Eerie with several horror stories. From 1960 to 1972, he did the daily 'Honor Eden' for the McClure Syndicate. Jack Sparling remained active until the late 1980s. In the final stages of his comic book career, he worked mainly on Western Publishing titles like 'The Twilight Zone' and 'Turok', but he also did contributions to DC and Marvel titles.
