In this marvelous anecdotal history, Justin Kaplan--Pulitzer Prize-winning biographer of Mark Twain--vividly brings to life a grand story from the glittering Gilded Age. Endowed with the largest private fortunes of their day, cousins John Jacob Astor IV and William Waldorf Astor vied for primacy in New York society, producing the grandest hotels ever seen in a marriage of ostentation and efficiency that transformed American social behavior. Kaplan exposes it all in exquisite detail, taking readers from the 1890s to the Roaring Twenties in a combination of biography, history, architectural appreciation, and pure reading pleasure
