Yvonne Craig was the very first live action incarnation of the iconic character of Batgirl. She joined the 60s Batman series for its third and final season. Her presence on the series managed to breath some new life into the series for the brief time that she was on.
Craig did all of her own stunts on the show, including the riding of the Batgirl cycle. She kept her secret identity as Commissioner Gordon's daughter and librarian a secret from the Caped Crusaders.
Batgirl did a great PSA for the Federal Equal Pay Law back in 1973.
Yvonne Craig passed away at the age of 78 on Monday night. She was at rest in her home, suffering from breast cancer that had metastasized to her liver.
