Bukovetsky (1881-1972), who worked for his long pedagogical and scientific activities in various universities in Petersburg (Leningrad). The emphasis is on Bukovetsky’s contribution to studying the history of Russian financial policy. It is noted that his work in the archive of the Special Chancellery on the credit side of the Ministry of Finance of Tsarist Russia in the mid-1920s. allowed to collect a unique material, as the archive funds were badly damaged during the Great Patriotic War. This circumstance makes the unpublished works of the scientist a valuable source for studying economic history. The Bukovetsky idea is shown on the basis of archival materials to highlight the financial relations between Russia and Turkey during the 19th and early 20 th centuries. in his doctoral dissertation „Essays on the history of financial relations of tsarist Russia and Turkey“ (1940).
