History San José’s (HSJ) activities began in 1949 following the centennial celebration of the California Gold Rush and statehood. Known initially as the San José Historical Museum, and managed by the City of San José, the museum was assisted by the non-profit San José Historical Museum Association, incorporated in 1971 to raise funds to support Museum projects. The non-profit became what is know known as History San José. Over the decades, the Museum has grown to include three sites: History Park, the Gonzales/Peralta Adobe — Fallon House Historic Site, and the Collection Center/Research Library & Archives.
