Art Nouveau is bracketed by two technologies and one war.
The technology that made it possible was chromolithographic colour printing at billboard scale. Jules Chéret had industrialised the four-stone process in Paris from the 1860s, printing six-foot posters that Parisian advertisers could paste directly to public hoardings. By the late 1880s the lithographic shops of Paris (Chaix, Cassan, the Imprimerie Bourgerie) were printing in editions of one to ten thousand. The blank Haussmannian wall became the canvas of the avant-garde.
The first wave of the graphic-design movement is conventionally dated from December 1894 and Alphonse Mucha’s overnight Gismonda poster for Sarah Bernhardt. Mucha — a 34-year-old Czech painter working as a hired hand at the Lemercier lithographic shop — drew the poster in three days when no other designer was available over Christmas. Bernhardt signed him to a six-year contract on the strength of it. By 1898 his name was a style.
In parallel, Henri de Toulouse-Lautrec had been producing poster work for Montmartre cabarets since Moulin Rouge — La Goulue in 1891. His later posters for Le Divan Japonais, Aristide Bruant and the Folies-Bergère singer Jane Avril define the more austere, flat-colour, Japanese-print-influenced branch of the movement.
In London, Aubrey Beardsley was already publishing in The Studio (founded 1893) and The Yellow Book (1894–1897). His Salomé illustrations (1894) and Le Morte d’Arthur edition (1893–1894) carried the movement’s English wing. He died of tuberculosis in 1898, aged 25.
In Vienna, the Secession — Klimt, Moser, Olbrich, Hoffmann — broke away from the conservative Künstlerhaus in 1897. Ver Sacrum launched as the group’s journal in January 1898. Munich had Jugend magazine (founded 1896 — the source of the German word Jugendstil) and Otto Eckmann’s posters. Brussels had Henry van de Velde (later a founding figure of the Bauhaus lineage) and Victor Horta. Catalonia had Modernisme (Domènech i Montaner, Gaudí, Ramon Casas).
The peak years were 1895–1905. The 1900 Paris Exposition Universelle — with its Guimard métro entrances and its full decorative-arts pavilion — was the movement’s institutional apogee. By 1907 a reaction had set in: the Wiener Werkstätte (founded 1903) was already simplifying ornament towards geometric abstraction, and the Deutscher Werkbund (1907) was arguing for industrial standardisation.
The First World War ended Art Nouveau as a living movement. Mucha left Paris for Czechoslovakia and spent the rest of his life on the Slav Epic paintings. Beardsley was long dead. Klimt and Moser died in 1918. The post-war design conversation moved to Weimar — to the Bauhaus — and to Moscow.
