paragraph: Pushkin is usually credited with developing Russian literature. Not only is he seen as having originated the highly nuanced level of language which characterizes Russian literature after him, but he is also credited with substantially augmenting the Russian lexicon. Where he found gaps in the Russian vocabulary, he devised calques. His rich vocabulary and highly sensitive style are the foundation for modern Russian literature. His accomplishments set new records for development of the Russian language and culture. He became the father of Russian literature in the 19th century, marking the highest achievements of 18th century and the beginning of literary process of the 19th century. Alexander Pushkin introduced Russia to all the European literary genres as well as a great number of West European writers. He brought natural speech and foreign influences to create modern poetic Russian. Though his life was brief, he left examples of nearly every literary genre of his day: lyric poetry, narrative poetry, the novel, the short story, the drama, the critical essay, and even the personal letter. Pushkin's work as a journalist marked the birth of Russian magazine culture which included him devising and contributing heavily to one of the most influential literary magazines of the 19th century, the Sovremennik (The Contemporary, or Sovremennik). Pushkin inspired the folk tales and genre pieces of other authors: Leskov, Esenin, and Gorky. His use of Russian language formed the basis of the style of novelists Ivan Turgenev, Ivan Goncharov, and Leo Tolstoy, as well as that of subsequent lyric poets such as Mikhail Lermontov. Pushkin was analyzed by Nikolai Vasilyevich Gogol, his successor and pupil, and the great Russian critic Vissarion Grigoryevich Belinsky who has also produced the fullest and deepest critical study of Pushkin's work, which still retains much of its relevance.
