Walt Disney’s only biological child died today at her home in Napa, CA, of complications from a fall in September. Diane Disney Miller was 79. She was a driving force behind the construction of the Walt Disney Concert Hall in downtown L.A. Her husband of nearly 60 years, Ron W. Miller, is a former CEO of Walt Disney Productions. Here’s a statement on her passing from Disney president and CEO Bob Iger: “We are deeply saddened by the loss of Diane Disney Miller and our thoughts are with her family during his difficult time. As the beloved daughter of Walt Disney and one of his inspirations for creating Disneyland, she holds a special place in the history of The Walt Disney Company and in the hearts of fans everywhere. She will be remembered for her grace and generosity and tireless work to preserve her father’s legacy, and she will be greatly missed by all who knew her.”
