Concept and creation
The Hulk first appeared in The Incredible Hulk #1 (cover dated May 1962), written by writer-editor Stan Lee, penciled and co-plotted by Jack Kirby, and inked by Paul Reinman. Lee cites influence from Frankenstein and Dr. Jekyll and Mr. Hyde in the Hulk's creation:
It was patently apparent that [the monstrous character the] Thing was the most popular character in [Marvel's recently created superhero team the] Fantastic Four. ... For a long time I'd been aware of the fact that people were more likely to favor someone who was less than perfect. ... It's a safe bet that you remember Quasimodo, but how easily can you name any of the heroic, handsomer, more glamorous characters in The Hunchback of Notre Dame? And then there's Frankenstein ... I've always had a soft spot in my heart for the Frankenstein monster. No one could ever convince me that he was the bad guy. ... He never wanted to hurt anyone; he merely groped his torturous way through a second life trying to defend himself, trying to come to terms with those who sought to destroy him. ... I decided I might as well borrow from Dr. Jekyll and Mr. Hyde as well—our protagonist would constantly change from his normal identity to his superhuman alter ego and back again.
Kirby, commenting upon his influences in drawing the character, recalled as inspiration the tale of a mother who rescues her child who is trapped beneath a car. Lee has also compared Hulk to the Golem of Jewish mythology. In The Science of Superheroes, Gresh and Weinberg see the Hulk as a reaction to the Cold War and the threat of nuclear attack, an interpretation shared by Weinstein in Up, Up and Oy Vey. This interpretation corresponds with other popularized fictional media created during this time period, which took advantage of the prevailing sense among Americans that nuclear power could produce monsters and mutants.
In the debut, Lee chose grey for the Hulk because he wanted a color that did not suggest any particular ethnic group. Colorist Stan Goldberg, however, had problems with the grey coloring, resulting in different shades of grey, and even green, in the issue. After seeing the first published issue, Lee chose to change the skin color to green. Green was used in retellings of the origin, with even reprints of the original story being recolored for the next two decades, until The Incredible Hulk vol. 2, #302 (December 1984) reintroduced the grey Hulk in flashbacks set close to the origin story. An exception is the early trade paperback, Origins of Marvel Comics, from 1974, which explains the difficulties in keeping the grey color consistent in a Stan Lee written prologue, and reprints the origin story keeping the grey coloration. Since December 1984, reprints of the first issue have displayed the original grey coloring, with the fictional canon specifying that the Hulk's skin had initially been grey.
Lee gave the Hulk's alter ego the alliterative name "Bruce Banner" because he found he had less difficulty remembering alliterative names. Despite this, in later stories he misremembered the character's name and referred to him as "Bob Banner", an
