Golden Age
In the first version during the Golden Age, Batman's first appearance in Detective Comics #27, he is already operating as a crime fighter. Batman's origin is first presented in Detective Comics #33 (Nov. 1939), and is later fleshed out in Batman #47. As these comics state, Bruce Wayne is born to Dr. Thomas Wayne and his wife Martha, two very wealthy and charitable Gotham City socialites. Bruce is brought up in Wayne Manor, with it's wealthy splendor, and lives a happy and privileged existence until the age of eight, when his parents are killed by a small-timed criminal named Joe Chill while on their way home from a movie theater. Bruce Wayne swears an oath to rid the city of the evil that had taken his parents' lives. He engages in intense intellectual and physical training; however, he realizes that these skills alone would not be enough. "Criminals are superstitious and cowardly lot," Wayne remarks, "so my disguise must be able to strike terror into their hearts. I must be a creature of the night, black, terrible..." As if responding to his desires, a bat suddenly flies through the window, inspiring Bruce to take on the persona of Batman.
This Cache is behind the Hollywood Theater in honor of Batman's origin story here. We figured that he and his folks had a fair walk (roughly 1/10 mile) before they met their fates.
