S. Annie (Sarah Annie) Frost

Writing as S. Annie Frost, Sarah Annie Frost was an American author active in the late 1860s and 1870s. Library of Congress records credit her with books such as Frost's Laws and By-Laws of American Society (1869), The Art of Dressing Well (1870), The Book of Tableaux and Shadow Pantomimes (1869), and Almost a Man (1877).

Her range was unusually broad. She wrote practical guides on etiquette and dress, books for home entertainment and amateur performance, and fiction and children's works, with publishers including Dick & Fitzgerald and the American Tract Society. A Smithsonian collection note on Frost's Dialogues for Young Folks describes that book as a set of short scenes for children to recite in parlors, churches, and schools, meant to entertain while teaching moral lessons.

Some library and museum records also identify her as Sarah Annie Frost-Shields, and Project Gutenberg lists "Shields, Sarah Annie Frost" as an alias. Clear biographical details beyond her published work are hard to confirm from the sources I found, but her surviving books show a writer closely attuned to the social customs, amusements, and self-improvement literature of her time.
