Alexander Lvovich Duvernois (1840-1886) - Russian linguist, Slavic. He was especially fond of comparative linguistics and Slavic philology, which resulted in his three articles: "On the Origin of the Varangians of Russia," "On the Year of the Invention of Slavic Letters" and "Tübingen Acts of Slavic Printing in Württemberg"). The first of these articles, especially valuable in terms of the successful grouping of data in favor of the Norman origin of the Varangians of Russia, is a student work competitive for the topic proposed by the faculty, awarded a gold medal by Moscow University and contains an abundance of linguistic material to resolve the issue of the origin of Russia and to explain the Russian names of the Dnieper rapids at Konstantin Bagryanorodny.
