Art Nouveau painters

Georges de Feure (real name Georges Joseph van Sluijters, 6 September 1868 – 26 November 1943) was a French painter, theatrical designer, and industrial art designer in the symbolism and Art Nouveau styles.
De Feure was born in Paris. His father was an affluent Dutch architect, and his mother was Belgian. De Feure had two sons, Jean Corneille and Pierre Louis, in the early 1890s with his mistress Pauline Domec and a daughter with his first wife Marguerite Guibert (married 7 July 1897).
In 1886, de Feure was one of the eleven students admitted at the Rijksacademie voor Beeldende Kunsten in Amsterdam, which he did however leave very quickly for Paris since he felt that formal academic training had nothing to offer him. Being of very independent nature, de Feure never again took up formal artistic studies, and forged his own independent path. He was however influenced by Jules Chéret in his posters for the café concert but most likely was never his pupil and became the key designer of Siegfried Bing for L'Art Nouveau.
He showed work in the Exposition Universelle de Paris exhibition in 1900. He designed furniture, worked for newspapers, created theater designs for Le Chat Noir cabaret and posters. In August 1901, de Feure was nominated Chevalier de la Légion d'honneur for his contribution to the decorative arts. He died in poverty at the age of 75 years in Paris.

Maurice Langaskens (born 1884 in Ghent — died 1946 in Schaerbeek) was a Belgian painter. His work was initially of the Art Nouveau style. Langaskens was prisoner of war when he painted his best known work, In Memorium: Burial of a Prisoner of War at the Gottingem Camp.

Fidus was the pseudonym used by German illustrator, painter and publisher Hugo Reinhold Karl Johann Höppener (October 8, 1868 – February 23, 1948). He was a symbolist artist, whose work directly influenced the psychedelic style of graphic design of the late 1960s.

Adolphe Léon Willette (30 July 1857 in Châlons-sur-Marne – 4 February 1926 in Paris) was a French painter, illustrator, caricaturist, and lithographer, as well as an architect of the famous Moulin Rouge cabaret. Willette ran as an "anti-semitic" candidate in the 9th arrondissement of Paris for the September 1889 legislative elections.

Franz Ritter von Stuck (February 23, 1863 – August 30, 1928), born Franz Stuck, was a German painter, sculptor, printmaker, and architect. Stuck was best known for his paintings of ancient mythology, receiving substantial critical acclaim with The Sin in 1892. In 1906, Stuck was awarded the Order of Merit of the Bavarian Crown and was henceforth known as Ritter von Stuck.
