Diane Disney Miller has passed away had the age of almost 80 (d.12/18/33). . Walt's only actual biological child (along with stepsister Sharon Disney, who already died in 1993), Diane was
one of the biggest fans of her own legendary dad in order to preserve the legacy of the Disney Archives and studio, and the

it did aggravate it. She also helped a lot with the Disney Family Museum.
