The Addison Gallery’s collection of American art is one of the most comprehensive in the world, including nearly 22,000 objects spanning the 18th century to the present. In a typical year, the Addison presents approximately twelve shows, including both permanent collection installations and major traveling exhibitions, carefully balanced to represent a wide range of art, across time and media. The Addison has also organized numerous nationally touring exhibitions, including shows such as American Vanguards: Graham, Davis, Gorky, de Kooning and Their Circle, 1927 – 1942 and Coming of Age, as well as retrospectives dedicated to artists such as John Marin, Sheila Hicks, William Wegman, Trisha Brown, Carroll Dunham, Wendy Ewald, Terry Winters, and Richard Stanciewicz. The Addison is committed to serving the public through free admission and an education outreach program that reaches diverse audiences, including teachers, students from pre-kindergarten through grade 12, and adults. All Addison education programs are offered free of charge. The Addison’s Museum Learning Center, in the new Sidney R. Knafel Wing, offers a flexible classroom and exhibition space that makes the entire collection accessible for programs tailored to the specific interests of individual groups. In addition to classes in art and art history, the Addison’s collection lends itself to use by history, math, and science classes. The Addison, which is free and open to the public, is located in a stand-alone building on the campus of Phillips Academy at the corner of Main Street and Chapel Avenue in Andover, Massachusetts, just 30 minutes north of Boston
