The memorial paper written to the 100th anniversary since the birth of O.M.Bogolyubov, a distinguished Ukrainian historian of science, contains an account of his life, scientific and teaching work, contributions in the development of studies on the history of mathematics in Ukraine. Also, details and a chronology of the rise and institutionalization of the history of mathematics on the territory of Ukraine, on the Academy grounds, are given. Details of Bogolyubov's work at the Academy of Sciences of Ukraine (where he came in 1962) are narrated in keeping with the chronology: 1963-1974 - when he worked in the sector for history of natural science and technology at the Academy's Institute for History; 1962-1963 and 1974-2004 - when he worked in the Academy's Institute for Mathematics. His teaching work began while he was a university student. He taught in the Kiev Institute for Civil Construction Engineering during 25 years. Also, in 1975, when working in the Institute for Mathematics, he launched the scientific seminar on history of mathematics and mechanics, having great importance for fostering his disciples and, in this way, establishing his academic school. Bogolyubov could contribute significantly in science history of mathematics and applied mechanics by scrutinizing earlier publications (from XVIII century and on). As a result, novel and unknown materials were brought to scientific circulation, about the logic and continuity in the development of mechanisms in the worldwide context, the respective roles of national and foreign scientists, unknown biographic data about most distinguished ones.
