Andrei Platonovich Klimentov (Russian: Андре́й Плато́нович Климе́нтов), known by the pen name Andrei Platonov (Russian: Андре́й Плато́нов), was a Soviet Russian novelist, short story writer, philosopher, playwright, and poet. Although Platonov regarded himself as a communist, his principal works remained unpublished in his lifetime because of their skeptical attitude toward collectivization of agriculture (1929–1940) and other Stalinist policies, as well as for their experimental, avant-garde form infused with existentialism. His famous works include the novels Chevengur (1928) and The Foundation Pit (1930).
