Steve Ditko is the third creator of the
Marvel Universe along with
Stan Lee and
Jack Kirby, who is most famous for co-creating
Spider-Man.
Unlike Kirby, whose work is like a grand symphony of grandiose spectacle and mythic archetypes, Ditko's work at its prime is more like a bluesy soloist, determined to follow his own vision to create his own path. As such, he took to Stan Lee's ideas for deeper characterization much more easily than Kirby did and carved out his own special niche into Marvel.
That means while Ditko was not as dominant in the company's work, his work stood out as something special, such as his original take on Spider-Man being so distinctively him that he was among the first to share official writing credits with Stan Lee on the comic as a plotter. Likewise, his surreal imagery of his
Doctor Strange stories have set the tone for the supernatural in the
Marvel Universe for decades. In addition, it was his
Incredible Hulk stories where the eponymous character first began to change when he is under extreme stress, turning the character from a
Jekyll and Hyde copy into the pop culture embodiment of runaway emotion.
Unfortunately, Ditko had a falling-out with Lee, possibly over the revelation of
Norman Osborn being Green Goblin. Supposedly, the Objectivist Ditko thought that criminals were pathetic losers and that the idea of a supervillain turning out to be a successful businessman was politically offensive (which is not much of an Objectivist viewpoint); another explanation suggests that
Ditko was unwilling to compromise on realism
while Lee pushed for a move towards "Marvel time"; and yet another explanation was that he simply thought it was unrealistic for Peter Parker to have known the villain in both his civilian and superhero persona. He defected back to
Charlton Comics where he would work on some of his classic secondary creations like designing
Captain Atom, revamping the
Blue Beetle and creating
The Question, which were all eventually purchased by
DC Comics in the 1980s. In 1960s, Ditko would later move to DC himself to create characters like
The Creeper,
Hawk and Dove, and
Shade, the Changing Man.
Eventually, Ditko's storytelling shifted to push his
Ayn Rand influences and interest in Objectivism further into the open. Nowhere is that more obvious but in his
Mr. A stories about a
Black and White Morality vigilante (a less commercial version of the Question).
Alan Moore notably despised this character - the character of Rorschach in
Watchmen is a deconstruction and parody of these characters, though
some have missed Moore's point, thus resulting the parody becoming a superior interpretation of its intended victim whom even Ditko thought was faithful as an insane version of his own creation.
Today, his work has slowed down due to its inaccessibility and consistent reports of Ditko being difficult to work with in general. He has become the most famous
Reclusive Artist of the medium, refusing all interviews and photos even while he's getting his due with official credits in the
Spider-Man feature films and his DC/Charlton characters getting the spotlight in
Justice League Unlimited.
...oh yeah, and he created
Squirrel Girl. Make of that what you will.
