Its not your fault. Blame the publishing industry or Bob Kane or whoever you like..
The fact remains that Batman would be unrecognizable without Mr.Finger.
He’s the writer best known as the uncredited co-creator, with Bob Kane, of the DC Comicscharacter Batman, as well as the co-architect of the series’ development.
Finger offered such suggestions as giving the character a cowl instead of the domino mask, a cape instead of wings, adding gloves, and removing the red sections from the original costume.

heres a quick run through of why he should be important to every Batman fan.
He later said his suggestions were influenced byLee Falk‘s popular The Phantom, a syndicated newspaper comic strip character with which Kane was familiar as well, and that he devised the name Bruce Wayne for the character’s secret identity. As Finger described, “Bruce Wayne’s first name came from Robert Bruce, the Scottish patriot. Wayne, being a playboy, was a man of gentry. I searched for a name that would suggest colonialism. I tried Adams, Hancock … then I thought of Mad Anthony Wayne.” Kane decades later in his autobiography described Finger as “a contributing force on Batman right from the beginning… I made Batman a superhero-vigilante when I first created him. Bill turned him into a scientific detective.” Finger biographer Marc Tyler Nobleman described, “Bob [Kane] showed Bat-Man to [editor] Vin [Sullivan] — without Bill. Vin promptly wanted to run Bat-Man, and Bob negotiated a deal — without including Bill.”
