1886. In 1978, the Crocker Art Gallery was renamed the Crocker Art Museum. In 2002, to accommodate a burgeoning collection and the needs of the growing population of Sacramento and California's Central Valley region, the museum commissioned the firm of Gwathmey Siegel & Associates to design a major addition. The greatly expanded Crocker Art Museum opened on October 10, 2010. Permanent collections Californian art and American art The Californian art collection includes works dating from statehood to the present. The core collection of early Californian art was assembled by Judge E. B. and Margaret Crocker in the early 1870s. Prominent in their collection are works by the German-American artist Charles Christian Nahl, who brought the large scale and copious detail of European history painting to works depicting the California Gold Rush. The Crockers commissioned five major works from Nahl, including Sunday Morning in the Mines (1872). The Californian collection continued to expand, and now contains 150 years of painting, sculpture, and craft media covering genres that include Impressionism, Abstract Expressionism, and Pop Art, and features artists including early Sacramento painter Amanda Austin, Norton Bush, William Keith, Thomas Hill, Granville Redmond, Edwin Deakin, Guy Rose, Gottardo Piazzoni, Joan Brown, Elmer Bischoff, Roland Petersen, David Park, Jess, Richard Diebenkorn, Mel Ramos, and Wayne Thiebaud. The collection also includes American art from the late 19th century to the present. American impressionists and modernists are a particular strength, with artists including Childe Hassam, Robert Henri, Georgia O'Keeffe, Maynard Dixon, Marsden Hartley, Hans Hofmann, and Luis Cruz Azaceta. European art Original collection The collection of European art began with the Crocker family's trip to Europe, from 1869 to 1871. It was not a Grand Tour. The Crockers rented lodgings in Dresden for over a year, and traveled mostly in Germany. As a later director of the museum would write, "Mr. Crocker was a novice and completely susceptible to a kind of fraud in his anxiety to become the possessor of a large collection of masterpieces. He acquired in his wholesale search a collection of more than 700 paintings," most of them "not by the few famous names given him by the dealers in Munich and Dresden." (Works said to be by Rembrandt, Rubens, Poussin, Salvator Rosa, and even Leonardo da Vinci appear in the initial 1876 catalogue, but were reattributed in following decades.) However, among Crocker's purchases were a number of genuinely rare works by
