French Painter, 1724-1780,Draughtsman, etcher and painter, brother of (1) Charles-Germain de Saint-Aubin. He studied with the painters Etienne Jeaurat and Hyacinthe Colin de Vermont, but failed three times to win the Prix de Rome (competition paintings, 1752-4; Paris, Louvre). He broke with the Academie Royale, preferring to support and exhibit at the Academie de St Luc. Although he continued to paint such pictures as a Street Show in Paris (c. 1760; London, N.G.; other examples in Rouen, Mus. B.-A.), he is best known as a draughtsman and etcher. He was a passionate and unconventional observer of the sights of the Paris streets and of the social scene. Dacier saw him as the 'man who drew at all times and in all places', and his contemporary Jean-Baptiste Greuze spoke of his 'priapism of draughtsmanship'. In his many drawings he combined pencil, black and red chalk, bistre, ink and watercolour to create dazzling spontaneous effects. He drew incidents that struck him as he wandered the streets, or entertainments that he attended. He recorded them, noting dates and times, in sketchbooks (e.g. Paris, Louvre and Stockholm, Nmus.) or sometimes in the margins and blank pages of printed books that he was carrying (such as a volume of the poems of Jean-Michel Sedaine, in the Mus. Cond?, Chantilly). These drawings of contemporary incidents include the Fire at the Foire Saint-Germain on the Night of 16-17 May 1762 (ex-David Weill priv. col.) and the Crowning of Voltaire at the Theetre-Franeais in 1778 (Paris, Louvre; see fig.). He went regularly to the Salon of the Academie Royale and to art sales, covering the margins and flyleaves of his sale catalogues and Salon livrets with tiny sketches of works of art and the passing scene. One hundred of these illustrated catalogues were among his effects when he died, and of these about a third survive. These include the livrets for the Salons of 1761, 1769 and 1777 (all Paris, Bib. N.), as well as the catalogues of the sales of Louis-Michel van Loo in 1772 and Charles Natoire in 1778 (both Paris, Bib. N.), and that of Pierre-Jean Mariette in 1775 (Boston, MA, Mus. F.A.). Together with his etchings and large watercolours (e.g. Paris, Louvre) of the Louvre's Salon Carre at the time of the exhibitions of 1753, 1767 and 1769,
