Aleksei Yeliseyevich Kruchyonykh was a Russian poet, artist, and theorist, perhaps one of the most radical poets of Russian Futurism, a movement that included Vladimir Mayakovsky, David Burliuk and others. Born in 1886, he lived in the time of the Russian Silver Age of literature, and together with Velimir Khlebnikov, another Russian Futurist, Kruchenykh is considered the inventor of zaum, a poetry style utilising nonsense words. Kruchonykh wrote the libretto for the Futurist opera Victory Over the Sun, with sets provided by Kazimir Malevich. In 1912, he wrote the poem Dyr bul shchyl; four years later, in 1916, he created his most famous book, Universal War.
