After Mrs. Astor’s death in 1908 no real New York social leader came forth to take her place. In fact, New York had no real arbiter of comme il faut until 1922, when Emily Post’s Etiquette was published. Though Etiquette became a national bible of manners, the setting of the book is very much New York. The famous Post characters—the aristocratic Wellborns, Oldnames, Titheringtons and Kindhearts—are all New Yorkers. So are the ostentatious Miss Millions, the penny-wise Miss Smallpurse, the haughty Mrs. Toplofty and the somewhat raffish Mr. and Mrs. Worldly and Bobo Gilding. Some were even identifiable. (Bobo Gilding reminded many people of fun-loving Willie K. Vanderbilt.) … Mrs. Post made at least one condescending allusion to West Siders in her book, calling them “the new spendeasy Westerns.”
