BILL Finger.
I forgot, what's the story behind this? Sometimes I see, 'Batman created by Bill Finger & Bob Kane'. Other times, 'Batman created by Bob Kane'.
But never, 'Batman created by Bill Finger'... why is that?
*I keep saying and writing BOB when I mean BILL...Hard to fight this programming.*
Because he got muscled out early.
Bob Kane was commissioned to make a new superhero to cash in on the Superman success.
Story is that he took some 'Flash Gordon' comic art and drafted over it a dark like character like Zorro. Finger took that rough sketch and made 'The Batman' you know today. He made him a detective, designed the cowl, gloves, belt (CSI Kit) and made the cape wrap around him like 'Sherlock Holmes.'
When Bob Kane submitted his work he never credited Finger with the work he did. National Comics aka DC Comics hired Finger as a writer from Kane's verbal acknowledgement. Finger created the origin from real police cases and went on to write for DC for the late 30's to the late 50's...Bob was a perfectionist though and he had several delays because he wanted Batman to have a real authentic crime grit feel in his early career....then go into the adventures of space and sci-fi as seen on 'Batman: The Brave And The Bold.'
Finger wanted Batman to be like Zorro, Sherlock and Teddy Roosevelt. He also wanted him to be a legacy hero and not an immortal hero.
Superman was suppose to be the immortal hero (DC had no plans of making him pass on his mantle) and Batman be the human that passes on a tradition of fighting crime, defending the innocent and being of the people. (Originally, DC was going to go this route)
Bob Kane got more coverage because he was a more outgoing person. While, Finger was more private and shy.
In many interviews throughout the years, Bob Kane was asked how did he come up with 'The Batman' storyline...Every interview he added and changed around details.
