The Lyon School (French: École de Lyon) is a term for a group of French artists, closely related to the British Pre-Raphaelite painters and poets. Recognized at the Salon of 1819, the school was consecrated 16 February 1851 by the creation of the gallery of painters from Lyon (galerie des Artistes lyonnais) at the Museum of Fine Arts of Lyon.
Jean-Baptiste Louis Guy, born March 8, 1824 in Lyon where he died February 17, 1888, is a French painter. A student of Claude Bonnefond and Antoine Duclaux at the Palais Saint-Pierre in the École des Beaux-Arts, he exhibited in Lyon from 1840 and at the Paris Salon in 1868. After the war of 1870, he was appointed professor at the École des Beaux-Arts by the mayor of Lyon Jacques-Louis Hénon.
His paintings are painted or drawn on very varied subjects such as portraits, landscapes or still lifes, but also animals.
