Costa Mesa's 60th Anniversary Celebration

CMHS Facebook Link


Monthly Program -

The Costa Mesa Historical Society is pleased to announce that historian Richard Duvall will be our speaker on Sunday May 21, 2017 at our annual Early California Days at the Diego Sepulveda Adobe in Estancia Park!


Richard Duvall has always been interested in local history. He recalls the day his interest sparked, while on a 4th grade field trip to Mission San Juan Capistrano. Over the years he amassed a collection of books and research materials. By the early 1980’s Richard began to really dig in. His research took him to the archives of Mission Santa Barbara and led him to begin writing a book in the early 1990’s about California history, from the Portola Expedition of 1769 to statehood, with a focus on Rancho Santiago de Santa Ana, its Adobes and families, in the area that is now northern Orange County.

Richard enjoys sharing his knowledge of early California history with museum visitors. In addition to serving as a lead docent for many years with the Diego Sepulveda Adobe, he has been involved with the Irvine Historical Museum, Santa Ana Historical Society, the O’Neill Museum of San Juan Capistrano, and the Ramon Peralta Adobe in Anaheim Hills among others.

Among his media appearances, Richard participated in a 2008 episode of California’s Gold hosted by Huell Howser focusing on the early days of Costa Mesa.

Richard will be speaking to us about the significance of the Diego Sepulveda Adobe, the history of the area, the archaeology, and the mayordomo's role in the Adobe's construction. 

So come bring a friend as we learn about this fascinating history in your own backyard!

Chris Jepsen, Guest Curator, presents Tiki in Orange County, on display in the Frank Mt. Pleasant Library of Special Collections and Archives. From architecture, décor and music to literature, theme parks and backyard luaus, the South Seas was a wildly popular theme throughout mid-twentieth century America. Artifacts, photographs, documents and music, offer a brief look at the origins of Tiki in the South Pacific, its interpretation in mid-century Orange County (and Southern California), and how both have inspired today’s Tiki revival. 

Location: Frank Mt. Pleasant Library of Special Collections and Archives, 4th Floor 

Exhibit hours are Monday through Friday 10:00 a.m. to 5:00 p.m.
