Work in RadioEdit
She first acted on radio for the BBC in 1945, preferring the medium as it gave her more time to look after her young family, and it continued to be the medium in which she was the most active throughout her career. She played roles in hundreds of series, serials and plays, including various Shakespeare productions; Mrs Dale's Diary, The Governor's Consort (a part written especially for her by Peter Tinniswood), The Mystery of Edwin Drood and The Horse's Mouth. For the latter two productions she won Best Actress at the 1991 Sony Awards. In 2004 she played Eurycleia in BBC Radio 4's acclaimed dramatization of The Odyssey.
In The Archers in 1951 her character Jane Maxwell was the original stumbling block to the engagement of Phil Archer and his future (first) wife Grace. In 1965 she played schoolteacher Elsie Catcher, and was a regular on the programme for two years until the character retired. In 1969 she returned as Lady Isabel Lander, before she finally came back in 1992 as Julia Pargetter.

In 1959 she had acted in a radio play opposite Richard Attenborough, and when he was making his first film as a director, 1969's Oh! What a Lovely War, he remembered her performance and cast her as the mother of the Smith family. Her first film role, the production won her a nomination as Best Supporting Actress at the British Academy Film Awards. She later appeared in two other films, Fragment of Fear (1970) and Vampire Circus (1972).
