Barthélemy Menn (20 May 1815 – 10 October 1893) was a Swiss painter and draughtsman who introduced the principles of plein-air painting and the paysage intime into Swiss art.
Menn was born in Geneva as the youngest son of four to Not (Rhaeto-Romance language form for Louis) Menn, a confectioner from Scuol in the canton of Grisons, and Charlotte-Madeleine-Marguerite Bodmer, the daughter of a wealthy farmer from Coinsins in the Canton de Vaud. Already at the age of twelve, Menn took drawing lessons from the little-known Jean Duboi (1789–1849), and later, he entered the drawing school of the Geneva Arts Society. The repeated claim that he was also a pupil of the famous enameller Abraham Constantin (1785–1855) appears to be erroneous. In 1831, Menn was second in the annual drawing competition of the Geneva Art Society. The following year, he entered the studio of the Swiss history painter Jean-Léonard Lugardon (1801–1884), who was a pupil of Baron Gros(1771–1835) and acquainted with Jean-Auguste-Dominique Ingres (1780–1867). There, Menn was educated in figure drawing and composition before heading for Paris, where, in fall 1833, he entered the studio of Ingres. He was, therefore, no beginner when meeting the master, but needed some polishing and refinement in his art. In a letter to his friend Jules Hébert, Menn reported on the new situation: ‘Everybody, even the eldest in the studio tremble before Mr. Ingres. One fears him a lot in such a way that his corrections have a great impact. He is of an extreme sensibility,’ while the education in Ingres’ studio has been described by Théophile Silvestre, as follows: 'The students spend half of their time studying nature and half studying the masters among which they are especially attached to Phidias, the bas-reliefs of the Parthenon, classical sculpture in general.’ This explains why among Menn's early works there are many copies after the Parthenon frieze that was accessible in Paris in a set of plaster casts at the École des Beaux-Arts since 1816. (Fig. 2). Menn also copied several works by Raffael, Titian (Fig. 3), Veronese and Rubens in the Louvre, and works by Ingres.
