Marcel Cachin (20 September 1869 – 12 February 1958) was a French Communist politician and editor of the daily newspaper L'Humanite.

Inessa Fyodorovna Armand (born Elisabeth-Inès Stéphane d'Herbenville; 8 May 1874 – 24 September 1920) was a French-Russian communist politician, member of the Bolsheviks and a feminist who spent most of her life in Russia. Armand, being an important figure in the pre-Revolution Russian communist movement and the early days of the communist era, had been almost forgotten for some time (due to deliberate Stalinist censorship, partly in consideration of her relationship with Lenin) until the partial opening of Soviet archives during the 1990s (despite this, many valuable sources regarding her life still remain inaccessible in Russian archives). Historian Michael Pearson wrote about her: "She was to help him (Lenin) recover his position and hone his Bolsheviks into a force that would acquire more power than the tsar, and would herself by 1919 become the most powerful woman in Moscow."

Robert Blum (10 November 1807 – 9 November 1848) was a German democratic politician, publicist, poet, publisher, revolutionary and member of the National Assembly of 1848. In his fight for a strong, unified Germany he opposed ethnocentrism and it was his strong belief that no one people should rule over another. As such he was an opponent of the Prussian occupation of Poland and was in contact with the revolutionaries there. Blum was a critic of antisemitism, supported the German Catholic sect, and agitated for the equality of the sexes. Although claiming immunity as a member of the National Assembly, he was arrested during a stay at the hotel "Stadt London" in Vienna and executed for his role in the Revolutions of 1848 in the German states.

Gustav Regler (25 May 1898 – 14 January 1963) was a German writer and journalist.
