The Addison Gallery of American Art was built in 1930 through the generous gift of Thomas Cochran. It is named for his friend Mrs. Keturah Addison Cobb. It also provided funds to purchase the art collection for the permanent collection. Included in the collection is the school's copies of the Audubon Double Elephant Folio of Birds and his lesser known Folio of Quadrupeds. This is an unattributed drawing of the gallery looking east from the Great lawn. It includes two panels on either side of the main doors which did not appear on the building.
