Our Story
The Hyperion Historical Alliance was founded in 2007 through a conversation between author Didier Ghez and Diane Disney Miller, the daughter of Walt Disney. Officially established as a 501(c)(3) non-profit in 2014, HHA is dedicated to preserving Disney history through member-initiated projects. Members with professional ties to Disney work diligently to identify and secure historically significant materials that are at risk of being lost.
