Intending a total artistic renewal starting from the most basic elements of writing and visual communication, Isidore Isou, assisted by
Gabriel Pommerand, organized the first
Lettriste manifestation in Paris, on 8 January 1946. During the premiere of dadaist and fellow Romanian
Tristan Tzara's play
La Fuit at the
Theatre du Vieux-Colombier, Isou shouted "Dada is dead! Lettrism has taken its place!" Through this and other similar stunts – as well as with the help of Jean Paulhan and
Raymond Queneau, who placed his work in
La Nouvelle Revue in April, 1947 – he came to the attention of
Gaston Gallimard, who then accepted his memoire "L'Agrégation d'un Nom et d'un Messie" for publication. In 1949, Isou published the novel
Isou ou la mécanique des femmes (
Isou, or the Mechanics of Women), inspired by his obsessions with the 16-year-old muse and later conceptual artist Rhea Sue Sanders. and sentenced to prison for eight months (his sentence was suspended); a fine of 2000 francs was imposed along with the destruction of all copies of a book which 1950s' French jurisprudence considered completely obscene. The same year, he also published the first of his works on political theory: ''Traité d'économie nucléaire: Le soulèvement de la jeunesse
(Treatise of Nuclear Economics: Youth Uprising''). Lettrism continued to grow as a movement, becoming less dependent on the work of Isou himself.
Maurice Lemaître, Jean-Louis Brau,
Gil J. Wolman and Serge Berna joined the group in 1950, with
Guy Debord joining in early 1951, after meeting the Lettrists at the 4th
Cannes Film Festival. Debord quickly became an important figure in the so-called left wing of the Lettrists, which were more politically active and overtly "dedicated to Marxist teachings and the critique of capitalist societies". In October 1952, while
Charlie Chaplin was on an extensive publicity tour for his film
Limelight, the Lettrist left wing, led by Debord, disrupted a press conference at the
Hôtel Ritz Paris and distributed a pamphlet called "Finis les pieds plats" ("No More Flat Feet!") through which they espoused their belief that "the most urgent expression of freedom is the destruction of idols, especially when they present themselves in the name of freedom", claimed that the "leaflet was an attack against a unanimous, servile enthusiasm" and that Chaplin was an "emotional blackmailer, master-singer of misfortune". Isou was an admirer of Chaplin's films and he considered the cinema legend to be undeserving of this attack. == Film ==
