Jean-Laurent Mosnier (; 1743 â 10 April 1808) was a French painter and miniaturist.
Court painter under the Ancien Régime, Mosnier began, from 1789, a brilliant career as society painter in London, Hamburg and St. Petersburg. Many times academician, he left considerable work and high quality, both in miniature painting.
Self-Portrait with Two Pupils, by Adélaïde Labille-Guiard, is thought to have been the basis for Mosnier's similar self-portrait with his young daughters. It is thought that his ambition was to clone the success of Labille-Guiard's painting.
