Bob Kane was born on October 24, 1915 in New York City, New York. In early 1939 had cam up with the idea for the "Bat-man" and later Bill Finger joined him. When they fist started out Finger said that he suggested that he wanted to give Batman cowl, a scalloped cap instead of wings, gloves, and leaving the mask to just have a mouth and eye holes to conceal his identity and make him mysterious. Also Finger got rid of the original red color from the first idea for Batman and gave him the gray-and-black color scheme. Bob Kane was the artist while Bill Finger was the writer. Bob Kane and Bill Finger got the idea of Batman from Zorro and Lee Falk's The Phantom.

After a few issues of Bill Finger was tired of Batman always thinking and never really talking with people. Then Finger had a conversation with Kane to give them the idea of Batman having a sidekick. When they thought of the idea they at first did not no what to call him or what he would do, then Jerry Robinson gave them the idea of a normal human boy who's name would be Robin taking after Robin Hood. After they then created Robin they then would also make the Joker. One day Robinson came in to the room with a Joker card and then Kane and Finger knew that they had a new character. Kane got the look of the character from the actor Conrad Veidt, the man who played the main character in the 1928 movie The Man Who Laughs based of the novel by Victor Hugo. Jerry Robinson takes the credit for coming up with the idea of the Joker because he was the one who had brought in the joker playing card. After many years Kane was not as known as he used to be. Kane wrote a book balled Batman and Me. Then he was supposed to have a cameo in the 1989 Batman movie but never got the chance because of scheduling problems.

Bob Kane died on November 3, 1998. His wife's name was Elizabeth Sanders Kane who appeared in several of the Batman movies. Bob Kane will forever be known as one of the two creators of Batman.
