Which television programme featured Aunt Harriet?

Harriet Cooper, best known simply as Aunt Harriet from the Batman television series, is a character that first appeared in the comic book Detective Comics #328 (June 1964).Created by writer Bill Finger and artist Sheldon Moldoff, the character is the maternal aunt of Bruce Wayne's ward, Dick Grayson.

Harriet Cooper had doted on her younger brother, John, and worshipped Dick as well. Tragically, however, Harriet's husband had been left an invalid after suffering a grave injury and Mrs. Cooper became the breadwinner for the household, working two jobs to make ends meet. Unable to care for Dick herself, the offer by Bruce Wayne to serve as the youngster's guardian seemed to be a godsend. Bruce, for his part, offered to provide Harriet with enough money to live a more comfortable life but the proud woman wouldn't hear of it. Fortunately, she never connected the generous checks related to Mr. Cooper's injuries with a certain Gotham millionaire.
