<P0-S0> Alexander Alexandrovich Blok (Russian: Алекса́ндр Алекса́ндрович Бло́к ; ] ; 28 November [O.S. 16 November] 1880 7 August 1921) was a Russian lyrical poet. <SEP> <P1-S0>  He is known best as the founder of Surrealism. <P1-S1>  His writings include the first "Surrealist Manifesto" ("Manifeste du surréalisme") of 1924, in which he defined surrealism as "pure psychic automatism". <P1-S2> André Breton (] ; 19 February 1896 – 28 September 1966) was a French writer, poet, and anti-fascist. <SEP> <P2-S0> Russian literature refers to the literature of Russia and its émigrés and to the Russian-language literature of several independent nations once a part of what was historically Rus', the Russian Empire or the Soviet Union. <P2-S1>  The roots of Russian literature can be traced to the Middle Ages, when epics and chronicles in Old Russian were composed. <P2-S2>  By the Age of Enlightenment, literature had grown in importance, and from the early 1830s, Russian literature underwent an astounding golden age in poetry, prose and drama. <P2-S3>  Romanticism permitted a flowering of poetic talent: Vasily Zhukovsky and later his protégé Alexander Pushkin came to the fore. <P2-S4>  Prose was flourishing as well. <P2-S5>  The first great Russian novelist was Nikolai Gogol. <P2-S6>  Then came Ivan Turgenev, who mastered both short stories and novels. <P2-S7>  Leo Tolstoy and Fyodor Dostoyevsky soon became internationally renowned. <P2-S8>  In the second half of the century Anton Chekhov excelled in short stories and became a leading dramatist. <P2-S9>  The beginning of the 20th century ranks as the Silver Age of Russian poetry. <P2-S10>  The poets most often associated with the "Silver Age" are Konstantin Balmont, Valery Bryusov, Alexander Blok, Anna Akhmatova, Nikolay Gumilyov, Osip Mandelstam, Sergei Yesenin, Vladimir Mayakovsky, Marina Tsvetaeva and Boris Pasternak. <P2-S11>  This era produced some first-rate novelists and short-story writers, such as Aleksandr Kuprin, Nobel Prize winner Ivan Bunin, Leonid Andreyev, Fyodor Sologub, Aleksey Remizov, Yevgeny Zamyatin, Dmitry Merezhkovsky and Andrei Bely. <SEP> <P3-S0> Philippe Soupault (2 August 1897, Chaville, Hauts-de-Seine – 12 March 1990, Paris) was a French writer and poet, novelist, critic, and political activist. <P3-S1>  He was active in Dadaism and later founded the Surrealist movement with André Breton. <P3-S2>  Soupault initiated the periodical "Littérature" together with the writers Breton and Louis Aragon in Paris in 1919, which, for many, marks the beginnings of Surrealism. <P3-S3>  The first book of automatic writing, "Les champs magnétiques" (1920), was co-authored by Soupault and Breton. <P3-S4>  In 1927 Soupault, with the help of his wife Marie-Louise, translated William Blake's "Songs of Innocence and Experience" into French. <P3-S5>  The next year, Soupault authored a monograph on Blake, arguing the poet was a "genius" whose work anticipated the Surrealist movement in literature. <P3-S6>  He directed Radio Tunis from 1937 to 1940, when he was arrested by the pro-Vichy regime. <P3-S7>  He fled successfully to Algiers.
