Style sapin
The style sapin (the French "sapin" means fir tree, but better translates to "conifer style") is a variation of Art Nouveau created in La Chaux-de-Fonds, Switzerland, by the Swiss artist Charles L'Eplattenier (1874–1946), a professor of the school of art and design in that town. The basic principle taught by L'Eplattenier was that art should be inspired by nature, in this case by the conifers, in particular fir trees, that covered the Jura Mountains around the town.
