Madge Blake (née Cummings; May 31, 1899 – February 19, 1969) was an American character actress best remembered for her role as Larry Mondello's mother, Margaret Mondello, on the CBS/ABC sitcom Leave It to Beaver, as Flora MacMichael on the ABC/CBS sitcom The Real McCoys, and as Aunt Harriet Cooper in 96 episodes of ABC's Batman. Gene Kelly had a special affection for her and included her in each of his films following her role in An American in Paris. Early life Blake was born in Kinsley in Edwards County, south-central Kansas, to Albert Cummings and the former Alice Stone. Her father was a Methodist circuit rider who discouraged her from becoming an actress, thus she did not enter acting until later in life, despite her family's relocation from Kansas to Southern California. During World War II, Blake and her husband James Lincoln Blake worked in Utah on construction of the detonator for the atomic bomb and performed such jobs as testing equipment destined for the Manhattan Project. The couple received a citation for their work from the U.S. government. Blake was a first cousin of actor Milburn Stone (her mother and his father were sister and brother), who played the role of Doc Adams on Gunsmoke Western series. She did not begin to study acting until she was 50 years old, when she enrolled at the Pasadena Playhouse and took advantage of whatever influence or contacts Milburn Stone had to land acting roles. In the middle 1950s, Blake appeared on Rod Cameron's City Detective and in Ray Milland's sitcom Meet Mr. McNutley, renamed in the second season as The Ray Milland Show. Blake appeared in four episodes of the NBC sitcom It's a Great Life (1954–1956) and twice on CBS's December Bride, with Spring Byington. Acting career Blake portrayed gushy gossip columnist Dora Bailey in Singin' in the Rain (1952) and was a model for one of the fairies (Fauna) in Walt Disney's animated version of Sleeping Beauty (1959). She appeared as Mrs. Porter, a babysitter, in the 1959 pilot of CBS's Dennis the Menace. About this time, she was cast in a guest-starring role in the sitcoms Guestward, Ho!, with Joanne Dru on ABC, and Angel, with Annie Fargé on CBS. In 1960, she guest-starred in "Tom Cuts Off the Credit," the premiere episode of the sitcom The Tom Ewell Show starring Tom Ewell. In 1961, she guest-starred
