The museum was founded in 1969 by a small group of San Jose citizens who transformed the historic library building, scheduled for demolition, into a gallery focusing on modern and contemporary art.
Nine to twelve exhibitions are presented each year, from traditional painting to exploratory new‑media installations, including regional California works as well as the work of international artists.
In 1991, a new wing was added to the landmark 19th-century building, making way for the growing permanent art collection.
