J. G. (John Gustavus) Lemaistre

J. G. Lemaistre, identified in library and archive records as John Gustavus Lemaistre and noted as having died in 1840, is an obscure English-language author now known mainly through surviving editions of his books. The available records do not provide a full, reliable life story, so much about him remains uncertain.

He is associated with works including Frederic Latimer; or, The History of a Young Man of Fashion (published in 1799 and sometimes described in catalog records as only supposedly by him) and A Rough Sketch of Modern Paris, a book of letters describing society, manners, public curiosities, and amusements in the French capital during 1801–1802. Together, those titles suggest a writer interested in fashionable life, social observation, and the pleasures and performances of urban culture.

Because the surviving evidence is thin, the safest picture is of a minor author whose work still offers a window into the tastes of his time: sentimental fiction, social satire, and travel-inflected commentary for readers curious about modern life.
