The Disney Parks Blog announced that Disney Legend, Xavier "X" Atencio has passed away at the age of 98. Atencio began his career at Disney in 1938.
Atencio was an animator on classics like Pinocchio, Fantasia, and countless other films. He moved over to WED Enterprises (the division that became Imagineering) where he co-wrote classic attraction songs like Yo Ho (Pirates of the Caribbean) and Grim Grinning Ghosts (The Haunted Mansion).
He retired in 1984 but made several appearances at fan events and as a consultant. In the 2013 D23 Expo, Atencio was part of a panel discussion called, "Working with Walt". We have partial audio of that here.
