9. Myth: “Bob Kane is THE Creator of Batman.”
The Truth:
While we're on the subject of the Dark Knight, let's talk about Bob Kane. Bob Kane is kind of a jerk, you guys.
Bob Kane was the sole creator of Bat-Man, a red suited, domino mask-wearing guy with giant fake bat wings on his back. His partner, Bill Finger, turned Bat-Man into the Batman we all know, creating the costume, origin, pretty much all the villains, and literally everything else you know about Batman.
Kane drew the comic for a long time, though. How long? We don't know, because at some point, he began paying artist Sheldon Moldoff to draw the stories for him as a ghost artist. Signing his name on things other people did was kind of Bob Kane’s greatest skill.
But then why is he usually credited as Batman's only creator? Well, the truth was that Kane was an incredibly good businessman, who made sure his contract barred DC from ever crediting Finger as Batman's co-creator. Kane would also go on to claim credit for everything he didn't do, despite mountains of evidence. If you need to know who Bob Kane really was, read the infamous clown story, which is a bit too long to re-write here, so I'll link to it here.
