The Irvine Museum celebrated its 20th anniversary on Jan. 31 with the exhibition “Lasting Impressions: Twenty Years of The Irvine Museum,” which is on display through June 6 and features the best works from its collection of California impressionist paintings. The more than 300 guests at the anniversary celebration sipped Champagne and enjoyed hors d’oeuvres while appreciating some of the museum’s most popular artworks on display, including works by Franz A. Bischoff (1864-1929), George Brandriff (1890-1936) and Alson S. Clark (1876-1949), among many others. Founded by Joan Irvine Smith, Athalie Richardson Irvine Clarke and James Irvine Swinden (the museum’s current president), along with California impressionism expert Jean Stern as executive director, The Irvine Museum opened its doors on Jan. 15, 1993. Since its inception, the museum has not only been dedicated to preserving the California impressionism period (1890-1930) but also safeguarding an important piece of the state’s history. —A.T.
