Henri Barbusse (1873 - 1935) was a French novelist and a member of the French Communist Party. He was a lifelong friend of Albert Einstein. The Russian Revolution had significant influence on Barbusse's life and work. He joined the French Communist Party in 1923 and later traveled back to the Soviet Union. His later works, Manifeste aux Intellectuels (Elevations) (1930) and others, show a more revolutionary standpoint. Of these, the 1921 Le Couteau entre les dents (The Knife Between My Teeth) marks Barbusse's siding with Bolshevism and the October Revolution. Barbusse characterized the birth of Soviet Russia as "the greatest and most beautiful phenomenon in world history." The book Light from the Abyss (1919) and the collection of articles Words of a Fighting Man (1920) contain calls for the overthrow of capitalism. In 1925, Barbusse published Chains, showing history as the unbroken chain of suffering of people and their struggle for freedom and justice. In the publicistic book The Butchers, he exposes the White Terror in the Balkan countries.
