Abstract
At the present stage, historians are actively discussing the problems of relationships and mutual influences of history and biography. In our opinion, this is explained by noticeable changes in historical science, which have caused significant reorientations of research interests, the discovery of new subjects and topics of biographical research, as well as new directions and methods. Taking these factors into account, this article attempts to consider some of the most frequently discussed theoretical and methodological problems, including the modern ideas of historians about biography, its goals and objectives, the role and significance of biographical research for historical science. If you look closely at the history of the twentieth century, the Kazakh intelligentsia has given birth to many outstanding, bright personalities, and one of them is Khairetdin Bolganbaev. In this regard, in the article, based on the biographical method, the authors identified the place and role of Kh. Bolganbaev in the reconstruction and development of Kazakh society at the beginning of the 20th century.
