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.

We wanted you to be among the first to be aware that the Historical Society has just released its second book on Costa Mesa History, covering the years 1940-2003.  The book tells the story of Costa Mesa’s growth from infancy to its coming of age.
The book is available at the Costa Mesa Historical Society, 1870 Anaheim Ave, 949-631-5918,
From the back Cover: Perhaps no one could have foreseen the amazing transformation of Costa Mesa from a sleepy rancho to today’s bustling “City of the Arts.”  Along with other Orange County cities, Costa Mesa experienced explosive growth, redevelopment, county bankruptcy, traffic, and environmental issues.  While navigating these events, Costa Mesa emerged with its own brand of Southern California cityhood


Give the gift of history and help support the CMHS at the same time!

Lots of books and memorabilia to select from including commemorative plates, paperweights and SAAAB items, note paper, postcards and out of print items.

And we have many historic photos to choose from for your home, office or gift!
