She also transformed a rather pedestrian series of five-minute children's programmes the BBC had acquired from France into what became a cult classic, The Magic Roundabout.
Her long-standing interest in theatre and acting prompted Eason to apply for a position at the BBC in 1934, where she was interviewed by John Reith.
Her significant breakthrough came in 1964 with Vision On, which instead of ghettoising the deaf was designed to appeal to all children, with its emphasis on the visual arts such as mime, painting and drawing.
