The Society of California Pioneers

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 the academic community and the public.

As the oldest organization west of The Mississippi, The Society opened one of the first libraries in California, as well as a grand hall for meetings,

lectures, and social events. Today we operate a museum on The Main Post of The Presidio of San Francisco, free museum education programs, and The Alice Phelan Sullivan research library, all as a nonprofit organization designed to support scholarship and to encourage new interpretations that both illuminate and honor the diverse experiences of those who came before us.
