California Historical Society

The California Historical Society was founded in 1871 to inspire and empower people to make California’s richly diverse past a meaningful part of their contemporary lives. Our latest exhibition
Experiments in Environment: The Halprin Workshops, 1966-1971 presents the interdisciplinary workshops hosted by the architect Lawrence Halprin and his wife the avant-garde dancer Anna Halprin in San Francisco, Marin, and Sea Ranch. In the spirit of this exhibition, we will create our own San Francisco History Days score How did you arrive?.
