A richly detailed history of the baronial splendor of the Philadelphia Main Line estate Ardrossan and of the Montgomery family who built it. Real-life American counterparts of the Granthams of Downton Abbey, the Montgomerys are best known as the family on which Philip Barry based his 1939 play, The Philadelphia Story, featuring Katharine Hepburn who also starred in the later Hollywood film. The Montgomerys entertained in the grand manner, hosting fox hunts and dinner dances. Guests included diplomat W. Averell Harriman; First Lady Edith Roosevelt; and famed vaudevillians the Duncan sisters. The magnificent estate, still owned by the family, encompassed roughly 760 acres at its height. Located at its center is a magnificent 50-room Georgian style manor house. Essentially unaltered since 1913, the family home designed in 1911 by Horace Trumbauer, one of America's foremost classical architects, stands as a glorious reminder of the halcyon days of the Gilded Age. The first-floor rooms, decorated by the London-based firm of White, Allom, & Company, feature the family's art collection, including works by Gilbert Stuart and Charles Morris Young. The book also chronicles the history of the family's commercial dairy and prized herd of Ayrshires. Features never-before-published architectural drawings from Horace Trumbauer's office and interior photographs shot by Mattie E. Hewitt in the 1930s; as well as family snapshots and images by celebrated photographers Cecil Beaton and Toni Frissell commissioned by Vogue and Country Life. This intimate portrait captures the elegant lifestyle of the Montgomerys and the majesty of their beloved home and estate, Ardrossan.
