Paul GAUDIN (1858-1921, engineer and archaeologist, an important figure in the history of the Chemin de Fer and one of the Louvre Museum's greatest donors of archaeological works) / Important collection of over 300 drawings and "crobars" by Paul Gaudin, in all formats, mostly on reused paper, Some of his sketchbook pages date from the 1860s, and are early drawings (in the 1870s, he was at the Lycée Saint-Louis in Paris, and was already enjoying sketching his classmates and teachers; later, as a young engineer, At the end of the 1870s, he joined the Chemins de Fer de l'Ouest, in Rambouillet and Epernon, then in the 1880s, at the Alençon railway station, he applied himself, as a dilettante, to sketching all the people around him, He was a good portraitist, and it's easy to see why his mastery of drawing later enabled him to produce invaluable archaeological records - some of his portraits are on the back of his visiting cards, another on the back of a British South Coast Railway ticket, and many are by name (Alba, Cherbourg stationmaster, Buhon, mechanic of the Courville rotting machine, Mr. Yvart notary in Alençon, etc.).), he likes to caricature the politicians of his time (Jules Ferry, Grévy, etc.), and draws scenes of magic lantern projections (one is reused on a fragment of a letter addressed to Fulgence Bienvenüe), all very lively.
