Established in 1850, the Society of California Pioneers is dedicated to the study and enjoyment of California art, history, and culture. Founded by individuals arriving in California before 1850 and thriving under the leadership of several generations of their direct descendants, The Society has continuously served its members, the academic community, and the public. As the oldest organization West of The Mississippi, The Society opened the first library in California, as well as a grand hall for meetings, lectures, and social events. Today The Society operates a public museum and a research library, both housed in one of the iconic Montgomery Barracks Buildings on The Presidio of San Francisco’s historic Main Post.
Pioneer Hall features rotating exhibitions of art and artifacts amassed since 1850; free museum education programs for school-aged children, as well as public tours and events are offered. The Alice Phelan Sullivan Research Library, which houses a large portion of The Society’s collections, is open to the public by appointment, allowing researchers and historians access to The Society’s privately held repository of rare primary source materials.
The Society's service to the community is designed to support scholarship and encourage new interpretations that illuminate and honor the diverse experiences of those who came before us.
According to its constitution, The Society's mission is "to cultivate the social virtues of its members, to collect and preserve information connected with the early settlement and conquest of the country, and to perpetuate the memory of those who sagacity, enterprise, and love of independence induced them to settle in the wilderness, and become the germ of a new State."
The Society continues to be a membership organization, and "Membership is open to descendants of pioneers who arrived in California prior to January 1, 1850."
The Society continues to exist and has its headquarters in San Francisco as it always has been. Pioneer Hall at The Presidio, which includes a museum (open to the public Wednesday to Sunday) and a research library (open by appointment only) is on the historic Main Post at 101 Montgomery, Suite 150 - Presidio of San Francisco, 94129.
The Society of California Pioneers’ archives document the founding and early history of California, including The Gold Rush, The Earthquake and Fire of 1906, and other defining events. The collection includes manuscripts and letters, paintings, prints and drawings, photographs, books, maps, newspapers and journals, the business ledgers of mining and transportation companies, as well as historic artifacts and decorative objects. An extensive collection of overland and pioneer diaries includes those of John A. Sutter and a letter by Henry W. Bigler, both primary sources announcing the discovery of gold in California. Works by Carleton Watkins, Eadweard Muybridge, Lawrence & Houseworth, and Turrill & Miller are held in our archive of photographs, panoramas, and daguerreotypes. Particularly notable for its nineteenth-century holdings, the painting collection includes works by Thomas Hill, William Coulter, Jules Tavernier, and Maynard Dixon. Together with The Society’s collection of ephemera and prints, these form a vivid, visual record of life in California over time.
The museum exhibits art and artifacts from the Society's collections on a rotating basis.
Several Bear Flags were donated to the Society during the last half of the 19th century, including a flag which almost certainly was the Bear Flag which was lowered at Sonoma on July 9, 1846, when the U.S. Flag was first raised at that location. This same Bear Flag very well may be the original Bear Flag which was made at the beginning of the Bear Flag Revolt of June/July 1846. The donation records of the Society show that two Bear Flags were donated to the Society by California U. S. Senator Weller on September 8, 1855. For many years, the Society would carry the Bear Flag during Admission Day parades and also on Anniversaries of the Bear Flag Revolt. Unfortunately all of the Bear flags held by the Society were destroyed in April 1906 as a result of the earthquake and fires which destroyed the Society's Pioneer Hall. Luckily a few photographs of the flags which had been taken survived so that we know what the flags actually looked like. Also a duplicate of the Bear Flag was made in 1896, the 50th Anniversary of the Bear Flag Revolt, and this flag continues to be displayed at the Sonoma Barracks, in Sonoma, California.
