The man who made Lenin furious over philosophy, then died swapping his own blood: a forerunner of cybernetics

Every organisation, on achieving decisive influence in society, inevitably — regardless of how democratic its programme — tries to impose its own internal structure on the whole social order. Every collective recreates the social environment in its own image and likeness.

Bolshevik co-founder and Lenin's early philosophical rival. His 'Tektology,' a universal organizational science, made him a forerunner of systems theory and cybernetics. Founder of the world's first blood transfusion institute, he died in 1928 during an exchange transfusion self-experiment.

Vyborg Bolshevik organizer who turned the Women's Day protest into the February Revolution

On 28 February, hearing of the Provisional Government's formation, Kayurov shouted to the soldiers: "Comrades! Has the workers' blood been flowing in the streets of Petrograd for three days merely to exchange one landlord for another?"

A metalworker who joined the RSDLP in 1898, Kayurov was a Bolshevik organizer in Petrograd's Vyborg district who, on 23 February 1917, defied the party committee's caution and transformed the women textile workers' International Women's Day strike into a revolutionary general strike.

After heading the 5th Army's political department in the Civil War, he worked in economic administration until 1932, when he and his son founded the Union of Marxist-Leninists with Ryutin's platform, an open challenge to Stalin; he died in Kazakh exile in 1936.

The Bolshevik between revolution and the industrial plan

January 1937, in the dock at the second Moscow trial. The German writer Lion Feuchtwanger recorded: "I shall never forget how Georgy Pyatakov, a gentleman of medium height, middle-aged, with a small bald patch and a reddish, old-fashioned, trembling pointed beard, stood before the microphone and calmly, diligently narrated how he had wrecked the industry entrusted to him. He explained, pointing with an outstretched finger, like a university lecturer — a historian delivering a report on the life and deeds of a long-dead man named Pyatakov, striving to clarify every detail, seized by the single desire that his listeners and students should understand everything correctly."

The only non-Bolshevik on all three leading Comintern bodies. And author of the first critical Stalin biography.

Ten days after the Bolsheviks seized power, the twenty-two-year-old Souvarine wrote on 17 November 1917: "It is to be feared that, for Lenin and his friends, the 'dictatorship of the proletariat' must be the dictatorship of the Bolsheviks and their leader. This could become a calamity for the Russian working class, and eventually, for the world proletariat. […] What we wish is agreement among socialists to organise a stable power that truly becomes the power of the people and not the power of a man." — 'La Commune maximaliste,' *Ce qu'il faut dire*, No. 78

The Trotskyist theorist who defined the USSR as bureaucratic state capitalism and built Britain's Socialist Workers Party

The slogan the Cliff group raised in 1950, when a handful of supporters brought out Socialist Review: “Neither Washington nor Moscow but international socialism.” It was a refusal of both camps of the Cold War, and the sentence that defined this current for the next half century.

Born Yigael Glückstein. Raised in Palestine in a family of Polish-Jewish immigrants, he left the Zionist left in his teens for Trotskyism, served twelve months in a British Mandate prison for anti-war agitation, and moved to Britain in 1947. In The Nature of Stalinist Russia (1948) he defined the USSR not as a degenerated workers'' state but as bureaucratic state capitalism, breaking with Fourth International orthodoxy, and on that base he built the theory of the permanent arms economy, which explained the postwar boom by East-West military spending, and of deflected permanent revolution, in which neither bourgeoisie nor working class but intellectuals and officers carry the revolution out. The organization he started as the Socialist Review Group in 1950 became the International Socialists and, in 1977, the Socialist Workers Party. He left a study of Rosa Luxemburg and four-volume biographies of Lenin and of Trotsky, and, never granted British citizenship, remained stateless all his life.

The exile historian of workers’ councils

In the resolution he recorded for 31 October, the workers' councils opened with 'The factory is the property of the workers.'

Balázs Nagy was a Hungarian revolutionary socialist and exile writer who documented how workers’ councils created an autonomous political and economic organisation outside the state apparatus and party bureaucracy during the 1956 revolution. He left a firsthand account of the formation of the Central Workers’ Council of Greater Budapest, its strike after 4 November, and its negotiations with the new government; the study was published in French in Brussels in 1961. His work shows both how working-class self-organisation functioned as an alternative political form amid defeat and the limits imposed on it by military intervention and repression.

A committed historian of revolutionary movements

He read Spain’s revolution not as a side episode of the war, but as a defeated social revolution.
