interest in the affairs of the organization, which included contributions to an endowment in excess of $2.5 million for an addition to the Indiana State Library and Historical Building in Indianapolis that would also house the Indiana Historical Society. Lilly attended dedication ceremonies for the building's four-story expansion in October 1976, a year before his death. Lilly and his brother also subsidized numerous projects and publications, including those related to archaeology, Indiana authors, Walam Olum, the paintings of George Winter, the diaries of Calvin Fletcher, and a Pulitzer Prize–winning history of the Old Northwest, among others. Upon his death, Lilly left the Indiana Historical Society a substantial endowment, making it one of the wealthiest organizations of its kind in the United States. Lilly's personal philanthropy also included contributions to the preservation and restoration of historic houses in Indianapolis and New Harmony, Indiana, and Shakertown, Kentucky. Lilly, along with other Hoosiers interested in preservation, founded the Historic Landmarks Foundation of Indiana (now Indiana Landmarks) to aid in the preservation of structures significant to the historical and cultural development of Indiana. In 1962, Lilly purchased, restored, and furnished Kemper house, a Victorian home in Indianapolis, saving it from demolition. Later that same year, HLFI purchased the Morris-Butler House, a home in the historic Old Northside neighborhood of Indianapolis, and with Lilly's help restored it to serve as a museum of mid-Victorian decorative arts and preservation education. With Lilly's assistance and a financial gift, the foundation also acquired the historic Huddleston farm in east-central Indiana in 1966 and restored its three-story, Federal-style brick home, which once served as a stop for travelers along the National Road. Lilly also purchased and contributed to the preservation of the William Conner home. His gift, in 1964, of this historic home in Hamilton County, Indiana, to Earlham College led to the development of Conner Prairie, an outdoor, living history museum. Lilly's interest in preservation led to involvement in other projects, including restoration of Crown Hill Cemetery's Waiting Station, the Indianapolis City Market, and the Lockerbie Square neighborhood in Indianapolis, among others. A lifelong resident of Indiana, Lilly was known for his deep affection for his home state. In addition to a primary residence in Indianapolis, Lilly owned three side-by-side large residences on Lake Wawasee in Kosciusko County, Indiana, just north of Our Lady Of The Lake Seminary. An avid sailor, he also assisted with the founding of
