Stanislav Vinaver was a Serbian writer, poet, translator and journalist. Vinaver was born to affluent Ashkenazi Jewish parents that had immigrated to Serbia from Poland in the late 19th century. He studied at the University of Paris, volunteered to fight in the Balkan Wars and later took part in World War I as an officer in the Royal Serbian Army. In 1915, he lost his father to typhus. He travelled to France and the United Kingdom the following year, delivering lectures about Serbia and its people. In 1917, he was assigned to the Serbian consulate in Petrograd, where he was to witness the Russian Revolution and its aftermath.
