De Valois kept her private life very distinct from her professional, making only the briefest of references to her marriage in her autobiographical writings. In April 1964 she was the subject of This Is Your Life, when she was surprised by Eamonn Andrews at the home of the dancer Frederick Ashton in London. She continued to make public appearances until her death in London at the age of 102.[citation needed]
