Caroline Marmon Fesler, president of the Art Association of Indianapolis, gave a number of artworks in the 1940s, including 20th-century modern artworks and Post-Impressionist works by Cézanne, Van Gogh, and Seurat.[5] After years of debate surrounding expansion and relocation of the museum and school, the great grandchildren of Eli Lilly, J.K. Lilly III and Ruth Lilly, donated the family estate, Oldfields, to the Art Association of Indianapolis in 1966. One year later the Art Association decided that the school would become a part of Indiana University's Indianapolis campus in an effort to assist with accreditation. That same year the Association confirmed that the museum would relocate to Oldfields, with the new Krannert Pavilion opening to the public in October 1970.
