Justice and Judges:
The History of the Law in Contra Costa County

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.

About the Exhibit

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.

CCCHS video at Lesher Foundation "Newsmakers" Speaker Series

On November 2, 2015, the Contra Costa County Historical Society was chosen to be the non-profit "partner" for that night's lecture in the "Newsmakers: Lesher Speaker Series" held at the Lesher Center in Walnut Creek. In addition to a generous donation of event tickets to the society, media sponsor KTVU Channel 2 sent a video crew to the Center to make a video highlighting some of our accomplishments. The 2 1/2 minute video was screened to the audience at the event, and a copy of the finished product was given to the Society to use as it sees fit. You may see the video shown that night by clicking on this link.

Looking for a gift for that hard-to-buy for history buff? The History Center offers a wide variety of books, photographs and services that they will just love. A membership in the Contra Costa County Historical Society makes a great gift too. For details on Society membership, whether for yourself or as a gift, please click here.
