passage: Batgirl
Schwartz stated that he had been asked to develop a new female character in order to attract a female viewership to the Batman television series of the 1960s.[6] Executive producer William Dozier suggested that the new character would be the daughter of Gotham City's Police Commissioner James Gordon, and that she would adopt the identity of Batgirl.[7] When Dozier and producer Howie Horowitz saw rough concept artwork of the new Batgirl by artist Carmine Infantino during a visit to DC offices, they optioned the character in a bid to help sell a third season to the ABC television network. Infantino reflected on the creation of Batgirl, stating "Bob Kane had had a Bat-Girl for about three stories in the ’50s but she had nothing to do with a bat. She was like a pesky girl version of Robin. I knew we could do a lot better, so Julie and I came up with the real Batgirl, who was so popular she almost got her own TV show."[8] Yvonne Craig portrayed the character in the show's third season.[9] Barbara Gordon and alter ego Batgirl debuted in Detective Comics #359, "The Million Dollar Debut of Batgirl" (1967). In the debut story, while driving to a costume ball dressed as a female version of Batman, Barbara Gordon intervenes in a kidnapping attempt on Bruce Wayne by the super villain Killer Moth, attracting Batman's attention and leading to a crime-fighting career. Although Batman insists she give up crime-fighting because of her gender, Batgirl disregards his objections.[10]
