The eldest daughter of Walt Disney and his wife, Lillian, Diane was intimately involved in her father's career: with her sister, Sharon, she introduced him to the Mary Poppins books of P L Travers and, in the years following Walt's death, stalwartly defended her father's reputation in the face of assaults by adversely critical journalists and biographers.
