Emily Post (October 27, 1872 – September 25, 1960) was an American author on etiquette.
Post was born as Emily Price in Baltimore, Maryland, into privilege as the only daughter of architect Bruce Price and his wife Josephine Lee Price of Wilkes-Barre, Pennsylvania. She was educated at home and attended Miss Graham's finishing school in New York, where her family had moved. She met a prominent banker named Edwin Main Post, her husband-to-be, at a ball in one of Fifth Avenue’s elegant mansions. Following a fashionable wedding and a honeymoon tour of the Continent (1892), Mrs. Post’s first home was in New York’s Washington Square. The couple had two sons, Edwin Main Post, Jr. (1893) and Bruce Price Post (1895). The couple divorced in 1905, because of her husband's affairs with chorus girls and fledgling actresses, which had made him the target of blackmail.
When her two sons were old enough to attend boarding school, she turned her attention to writing. She produced newspaper articles on architecture and interior design, as well as stories and serials for such magazines as Harper's, Scribner's, and The Century, as well as light novels, including Flight of the Moth (1904), Purple and Fine Linen (1906), Woven in the Tapestry (1908), The Title Market (1909), and The Eagle's Feather (1910).
