The Edward-Dean Museum opened in 1958, and was founded by Edward Eberle and Dean Stout. The Museum features late 16th to early 19th century European & Asian Decorative Arts. Dean Stout designed the interior spaces of the museum to create a home-like atmosphere with the intent to share with the visitor a first-hand experience of the ambiance of the time period. The museum and its 16-acre campus originally came under the county in 1964.
On July 1, 1999, the Edward-Dean Museum was shifted to the Economic Development Agency (EDA), a department of the County of Riverside, to manage. Rob Field, Assistant County Executive Officer/EDA, along with the Deputy Director, Marketing Director, and staff is handling the administrative operations. Historically the Friends of the Edward-Dean Museum, a not-for-profit organization with a board of directors, has been an ongoing champion of exhibits, preservation of the museum's permanent collection, and museum-specific projects.
