In the i922 original edition of Etiquette, Emily Post's guide to the practicesand manners of\"Best Society,\" 81 pages are devoted to all matters nuptial..There's a sad irony, then, to the fact that Emily Post became the foremostauthority on etiquette as the result of an unhappy marriage. In 1905, as biographerLaura Claridge recounts in Emily Post: Daughter of the GildedAge, Mistress ofAmerican Manners, Post's husband, Edwin, was the victim of a blackmail ployby a newspaper publisher who threatened to reveal Edwin's affair with a starlet.Edwin, who had lost much of his wife's inheritance playing the stock market, setup a sting to expose the publisher's scheme;then confessed to his wife who hadno choice but to support his decision. The successful sting, along with Edwin'sinfidelities, was widely reported. The publicity caused Emily much humiliation,and the couple divorced the following year.
