About the Authors
John grew up in Concord, CA, attended San Jose State University and earned a BA in Social Science with a concentration in history. John earned a master’s degree in public administration in 1985 and went on to a career in local government, retiring in 2006.
Since 1993, John has served on various boards and commissions including the Concord Planning Commission, Save Mount Diablo, East Bay Regional Park District Park Advisory Committee, and the California Recreational Trails Program Advisory Board. One of John’s most rewarding activities was writing a history of the Central Contra Costa Sanitary District to help celebrate the agency’s 50th anniversary. As a follow up to that work, he was asked to write a series of articles on the history of that agency and the local area. It was in the course of doing the research for these articles that he came to know and appreciate the resources of the Contra Costa County History Center. He currently serves as the President of the Contra Costa County Historical Society and resides in Concord, CA.
Steve retired after 32 years of service with the Federal government in the national security field, including 22 years with the Department of Energy. He has a master’s degree in Government from Georgetown University and received his undergraduate degree in Political Science from the University of California, Berkeley. He is a member of the Society for Military History and has written over 15 book reviews for the Journal of Military History. Steve is a long time resident of Dublin, CA.

Come see the Contra Costa County Historical Society's current exhibit, Justice and Judges: The History of the Law in Contra Costa County. The exhibit is in honor of Judge Richard Arnason and features artifacts and court documents that belonged to him, as well as a brief history of the Judicial system as it has evolved in Contra Costa County.
The exhibit is open to the public during our open hours, Tuesday-Thursday from 9AM to 4PM, as well as the third Saturday of each month from 10AM to 2PM.
The Society recently received a substantial donation from the Contra Costa County Superior Court. The donation consists of artifacts and court documents that once belonged to Judge Richard Arnason, who passed away in 2015 at the age of 94. Judge Arnason served as a Superior Court Judge for 49 years, longer than any judge in the history of the county.
He was also the judge in the Angela Davis trial, in 1972, arguably one of the most significant (for both legal and political reasons) cases of the latter 20th century.
The donation was received from Judge Barry Goode, who suggested that an exhibit honoring Judge Arnason would be welcomed. The Society's Executive Director also saw the potential for using the materials to educate the citizens of Contra Costa County, and thus, an exhibit was born.

We are making them available for sale, but please note that the quantities are quite limited and will be sold on a first-come, first-served basis.

CCCHS Past President and Curator of the San Ramon Valley Museum Beverly Lane has extended the great photos and research from our wildly successful exhibit on Electric Trains in Contra Costa County in 2012 into a booklet that the Society is proud to make available to the public.
