Ardrossan Mansion


He was born at Radnor in Delaware County, Pennsylvania. After serving in the Spanish–American War, he took it upon himself to replenish the family coffers and embarked on a financial career, co-founding the investment firm known today as Janney Montgomery Scott LLC. In 1913, he built Ardrossan on the Main Line, an estate of 800-acres where he was a conservationist and a dairy farmer with a prized herd of Ayrshire Cattle. He kept a pack of foxhounds and hunted with the Radnor Hunt. In later life, he developed a passion for aviation, helping to pioneer the autogyro. His wife was also his second cousin, both being great-grandchildren of the distinguished lawyer, Horace Binney. Their daughter, Hope Scott, was the inspiration for the character Tracy Samantha Lord in The Philadelphia Story and High Society.
