One of the major founders of the Russian Social Democratic Labor Party, which was the precursor of the Communist Party of Russia, Georgii Plekhanov led a life-long struggle alongside his comrades in growing the class consciousness of the workers and peasants of the Russian Empire. He supported the Bolsheviks over the Mensheviks and was a respected figure of authority by Lenin - even though they had disagreements - and the Communists.

While I'm not acquainted with any of his works nor knowledgeable on his biography, I do know that he had his good moments in history and his not so good moments in history, and that's okay.
