William "Bill" Finger was an American comic strip and comic book writer best known as the uncredited co-creator, with Bob Kane, of the DC Comics character Batman, as well as the co-architect of the series' development. In later years, Kane acknowledged Finger as "a contributing force" in the character's creation. Comics historian Ron Goulart, in Comic Book Encyclopedia, refers to Batman as the "creation of artist Bob Kane and writer Bill Finger", and a DC Comics press release in 2007 about colleague Jerry Robinson states that in 1939, "Kane, along with writer Bill Finger, had just created Batman for [DC predecessor] National Comics". Film and television credits include scripting The Green Slime (1969), Track of the Moon Beast (1976), and three episodes of 77 Sunset Strip. -Wikipedia
