Bill the Boy Wonder: The Secret Co-Creator of Batman 1st edition

Every Batman story is marked with the words "Batman created by Bob Kane." But that isn't the whole truth. A struggling writer named Bill Finger was involved from the beginning. Bill helped invent Batman, from concept to costume to character. He dreamed up Batman's haunting origins and his colorful nemeses. Despite his brilliance, Bill worked in obscurity. It was only after his death that fans went to bat for Bill, calling for acknowledgment that he was co-creator of Batman.
