Alexander Aleksandrovich Bogdanov, born Alexander Malinovsky, was a Russian and later Soviet physician, philosopher, science fiction writer and Bolshevik revolutionary. He was a polymath who pioneered blood transfusion and general systems theory and made important contributions to cybernetics.

The Bolsheviks, led by Vladimir Lenin, were a far-left faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split with the Mensheviks at the Second Party Congress in 1903. The Bolshevik party seized power in Russia in the October Revolution of 1917, and was later renamed the Communist Party of the Soviet Union. Their ideology and practices, based on Leninist and later Marxist–Leninist principles, are known as Bolshevism.
