Alexander Ivanovich Vvedensky (Александр Иванович Введенский; 1904–1941) was a Soviet poet with formidable influence on "unofficial" and avant-garde art during and after the times of the Soviet Union. Vvedensky is widely considered (among contemporary Russian writers and literary scholars) as one of the most original and important authors to write in Russian in the early Soviet period. Vvedensky considered his own poetry "a critique of reason more powerful than Kant's." Most of his works (most notably the novel "Murderers, you are fools") were for ever lost in the chaos of the World War II and as the result of the atmosphere of the period: people would destroy any doubtful manuscripts in their possession as incriminating evidence. The bulk of Vvedensky's extant works survived in the archive of Daniil Kharms. The archive itself was saved by Yakov Druskin, close friend of both poets, who, in the middle of the most deadly winter of Leningrad blockade, came to the abandoned and sealed apartment of arrested Kharms, removed the papers and preserved them all along. Most of Vvedensky's poetry was not widely known during his lifetime and not published in Russia until much later. He was known in small circles of writers in Leningrad — Anna Akhmatova praised one of his later poems, "Elegy," very highly. A two-volume collected works came out first in America, and then in Moscow in 1991.
