Batman: Year One
Batman (Bruce Wayne) is a superhero appearing in American comic books published by DC Comics who debuted in "The Case of the Chemical Syndicate", a story published in "Detective Comics" #27 (May 1939). He was created by artist Bob Kane and writer Bill Finger to capitalize on the success of DC's other superhero Superman and was inspired by characters from pulp fiction stories, such as the Shadow. Batman's origin story was introduced in a two-page, 12-panel story by Kane and Finger from "Detective Comics" #33 (Nov. 1939). In the story, a young Bruce witnesses the murder of his parents Thomas and Martha at the hands of a mugger. Bruce vows to avenge his parents' deaths by fighting crime; he takes the persona of Batman after a bat flies through his window one night. For the story, Finger lifted elements from tales published in "Popular Detective" and "The Phantom", while Kane traced artwork of Tarzan and from "Junior G-Men".
