Краковский лингвист Ян Розвадовский и Российская академия наук (по архивным документам) research-article Лариса Бондарь, Марина Поникаровская Wiener Slavistisches Jahrbuch. Neue Folge, Jahrgang 9 (2021), Ausgabe 1, Seite 174 - 190 Based on documents from the St. Petersburg and Cracow academic archives, the article highlights the interaction of Jan Rozwadowski (1864–1935) with Russian academic circles, which began with an appeal to V. I. Lamanskii for help in organizing a dialectical expedition to the Polish lands included into the Russian Empire. This first contact brought the Krakow professor to the St. Petersburg academic circles, and from this time began his productive communication with Russian linguists: F. F. Fortunatov, E. F. Karskii and, above all, A. A. Shakhmatov. It was this interaction that ultimately determined the double election of 1911: A. A. Shakhmatov – to the Polish Academy of Arts and Sciences, and J. Rozwadowski – to the Imperial Academy of Sciences. The First World War interrupted scientific contacts of colleagues, and J. Rozvadovsky did not resume epistolary communication with Russian (Soviet) Slavists after the war.
