Sheila Kuehl
Having landed the role at the age of eight Kuehl (billed as Sheila James) starred with radio and film veterans Penny Singleton, Gale Gordon, Bea Benaderet, and Jim Backus on the family radio program "The Penny Williamson Show" airing live from Studio B of the NBC studios in Hollywood. Airing in the adjacent studios was the popular drama "The Cisco Kid" and "The Bob Hope Show" with Doris Day (whom Kuehl admired). Kuehl would later cite her interaction with the other NBC radio talent as influential in forming her professionalism and comedy skills. The show centred around Singleton playing Penny Williamson a widow selling real estate in a small town to support two daughters (played by Kuehl and Mary Lee Robb). The show was "a light-hearted pitch for women's liberation, portraying Penny and her daughters as highly competent, self-sufficient females" dealing with bungling suitors competing for Penny's affections.
