Welcome to Millionaire’s Row, where the Gilded Age mansions and clubs of high society still exude a faded elegance. It was here that fiery Martha Wadsworth–avid sportswoman and social maven–and wealthy hostess Nellie Patterson mingled with the likes of famous inventor Alexander Graham Bell and miner-turned-millionaire Thomas Walsh. From the Union Station Plaza and Embassy Row to Dupont Circle and the Washington National Cathedral, author Mark N. Ozer examines the extant Beaux-Arts architecture of Massachusetts Avenue mansions and tells the tales of socialites and politicians who lived and played behind their grand facades.
