The article presents a study and the publication of the letters by the writer, historian, and art critic Genrich Pavlovich Gun’kin (1930–2006), also known under the pseudonym G. Gunn, to Vladimir Ivanovich Malyshev (1910–1976), Doctor of Philology, who was an outstanding archaeographer. A total of thirty-five letters covering the period from 1969 to 1976 are stored in the Manuscript Division of the Institute of Russian Literature (Pushkinskii Dom) of the Russian Academy of Sciences in St. Petersburg. Like a lot of Gun’kin’s books, all these letters are signed with his pen name «G. Gunn». The letters contain information both about Gun’kin’s achievements and difficulties that he encountered in his professional career. They also provide insight into the professional help that Malyshev rendered to Gun’kin when he wrote his books on the history and culture of the Russian North. Despite their modest place in Malyshev’s fonds, Gun’kin’s letters are important because they reflect some aspects of Malyshev’s life. From a larger perspective, they form a part of the multi-page epistolary epopee that is unfolding in the letters of hundreds of correspondents with the scholar, an epopee that gives insight into the life of Russian intelligentsia in the 1970s.
