After World War II, the Soviet regime led by Joseph Stalin began to distance itself from Western ideas and concepts, including science. Stalin declared genetics and cybernetics to be anti-Soviet and ideologically unfit; he put Lysenko in charge of the Academy of Agricultural Sciences of the Soviet Union and made him responsible for ending the propagation of "harmful" ideas among Soviet scientists. Lysenko served this purpose faithfully, causing the expulsion, imprisonment and death of hundreds of scientists and the demise of genetics (a previously flourishing field) throughout the Soviet Union. This period is known as Lysenkoism. Particularly, he bears responsibility for the death of the greatest Soviet biologist, Nikolai Vavilov, at the hands of the NKVD.
