The key scholarly issue of contemporary Ukrainian research is not only a return to existing problems and figures but also a search for new figures and the filling of historical and biographical gaps. The present article is dedicated to the biography of Kyiv Theological Academy graduate Serhii Hrushevskyi (1830–1901), a figure who has rarely appeared in research previously. He was a talented teacher and gained credibility and respect among his contemporaries. More attention should be paid to his publications in periodicals, (...) the themes of which varied from pedagogy to linguistics. It is necessary to emphasize the importance of Hrushevskyi in the development of public education of the late 19th century. The education, hard work, and active social activity of Serhii Hrushevskyi had a positive impact on his son, renowned Ukrainian politician and statesman, historian Mykhailo Hrushevskyi (1866–1934), for whom his father was his first and major mentor. Love for “Ukrainians,” learning and writing, selfless work – is the legacy that Serhii Hrushevskyi passed on to Mykhailo, which was always at the core of his life and scholarly activity. The results of the article not only contain new biographical information about Hrushevskyi’s family, but also emphasize the significant role of the biographical component in modern scholarly research.
