Fyodor Dmitrievich Kryukov was a Cossack writer and soldier in the White Army, died in 1920 of typhoid fever. Various literary critics, most notably Aleksandr Solzhenitsyn and Roy Medvedev, claimed that Mikhail Sholokov plagiarised his work in order to write major parts of And Quiet Flows the Don. This was also the conclusion of a statistical analysis by V. P. and T. G. Fomenko. Their conclusion has been questioned by a more recent analysis. Ze'ev Bar-Sela believes that although the book was plagiarised, it was plagiarised from Venyamin Alekseevich Krasnushkin, and not from Kryukov. A 1984 monograph by Geir Kjetsaa and others concluded through statistical analyses that Sholokhov was the likely author of Don.
