Serge Poltoratzky (alternate spellings: Sergei or Sergey and Poltoratsky, Poltoratskii or Poltoratskiy), 1803-1884, was a Russian literary scholar, bibliophile and humanitarian. His major literary work was the "Dictionary of Russian Authors", which he worked on for decades. He travelled extensively in Europe to find books and manuscripts needed for this work. He was also interested in the letters of Voltaire and in Franco-Russian cultural relations. He wrote articles for the French press on these and other literary topics, often under the pseudonym R.E. According to Yuri Druzhnikov, Poltoratzky was the first to introduce Pushkin's work to a western European audience, in the October 1821 issue of "Revue encyclopedique" (published in Paris).
