Russian poet and prose writer, one of the largest figures of Russian avant-garde. He was among the founders of Russian Futurism; a reformer of poetic language, an experimentalist in the field of word-creation. The highest estimate of Khlebnikov was given by Roman Jakobson, who knew him personally: "He was, in short, the greatest world poet of the present <twentieth> century...". In 1898 the family moved to Kazan, where he entered the 3rd Kazan Gymnasium. Five years later, he graduated from the gymnasium and, in the fall of 1903, entered the mathematics department of the physics and mathematics faculty of Kazan University. He eventually quit school to become a full-time writer. His earliest works are from 1908.
