After I looked through her IMDB filmography, I saw that she basically did voice work on a lot of the shows of my childhood. She was the voice of various characters in Denver The Last Dinosaur, The Smurfs, The Incredible Hulk (the 1982 cartoon, narrated by Stan Lee), and The Real Ghostbusters. She was the voice of Aunt May in Spider-Man And His Amazing Friends. Mrs. Featherby in both the Ducktales series, as well as Ducktales The Movie: Treasure of the Lost Lamp (1990).
She was the voice of the Talky Tina doll in an episode of The Twilight Zone.
She was in Rikki-Tikki-Tavi (1975) as the voices of Nagaina the Cobra, Wife of Nag; Teddy's Mother; and Darzee's Wife. I think that, and The Cricket In Times Square (1973) were on Nickelodeon a lot, too. She was the voice of the Hag in Faeries (1981), which I watched when I was likely only a year old--2 at the most...however old I was, a moment where a shadow is stabbed and starts bleeding left an impression, for I searched for it for decades before finding the title.
