Barbara Gordon (alias Batgirl) was portrayed by Yvonne Craig in the 1960s Batman TV series.
She is the daughter of Commissioner Gordon and works as a librarian by day. Unlike Batman, who is a millionaire with a vast mansion, Batgirl lives alone in an apartment - with a secret revolving wall that leads to a closet where she can change into her alter-ego and board her Batgirl-cycle, which is her main mode of transportation. As opposed to future adaptations of the character, Barbara has short, dark hair; the long, red hair usually associated with the character is a wig.
(From Batman Wiki) Barbara Gordon lived a normal life like any other young adult until she finished college and returned home to Gotham City. It was then that she decided to lend a hand to the cause of justice, perhaps inspired by her father's tales of the Dynamic Duo's exploits. Creating her own costume (she later won an award for best-dressed crimefightress in Gotham City) and Batgirl-cycle, she took the name Batgirl. A hidden button under her vanity activates a secret revolving door in her bedroom, which leads to the Batgirl-nook. From there, the Domino Daredoll would don her wig and change into the Batgirl costume. There is also another door, leading to the Batgirl-cycle, which exits the building through a secret freight elevator.
