The Grace Museum of America in Cave Creek, Arizona, sits in the mountains of the Sonoran Desert and focuses on American history over the past 200 years. Founded by Grace Voss Frederick, it grew from planning in the early 1980s to opening in the mid-1980s. Frederick, who lived from 1905 to 2009, saw it as a way to document America’s transformation from “a primitive country to a great nation,” drawing on objects she collected over a lifetime of travel. Supported by the nonprofit Grace Foundation for Preservation of Americana, it presents that story through guided tours using antiques, mannequins, and live and recorded interpretation arranged along a timeline.
