This study attempts to summarize the extensive biobibliographic material of the outstanding female scientist E. Dvoicenco-Marcova (1901–1980). As a special ethnocul-tural emphasis, facts are given regarding the scientist’s connections with the Museum of the Royal Funds (Bucharest), the Polish Society for Eastern European and Middle Eastern Studies (Warsaw), the Institute of Oriental and Slavic Philology and History of the Free Graduate School of Studies (New York), the Institute of World Studies Literature (Mos-cow). Eufrosinia Dvoicenco-Marcova is now known only to a narrow circle of specialists in Moldova and Romania, as a Pushkin scholar, a literary historian in the field of Roma-nian-Russian literary relations. Most of her works are related to the field of study of both famous Moldovan writers and Russians on Moldovan soil. It seems important to us, in the aspect of studying ethnocultural heritage, to represent the scientific path of the literary scholar E. Dvoicenco-Macova as a scientific phenomenon. Her first scientific research was done in Bucharest under the leadership of Nicolae Iorga and published under the name of her husband, the Russian officer Dvoicenco („Influenţa literaturii ruse asupra scriitorului Constantin Stamati”, Bucureşti, 1929). She worked extensively and fruitfully in Romania and published in the Romanian scientific press until the end of her life. After 1940, E. Dvoicenko-Marcova moved to the USA, where she continued to work on her topic (“Puškin and the Rumanian Historical Legend”, Cambridge University, 1948). In 1957, E. Dvoicenko-Marcova left the USA and went to the USSR, where she continued to work on studying Russian-Romanian literary connections in the first half of the 19th century. The biography of this woman is the difficult fate of a person who went through the trials of revolutionary upheavals, the destruction of ideological canons, war and repres-sion. The scientific heritage of Dvoicenko-Markova – the difficult path of a scientist whose geographical boundaries of scientific publications are on a global scale – shows the characteristics of a historical and cultural phenomenon.
