Aim: The aim of this article is to present the profile of Prof. Karol Poznanski and his scientific and organisational achievements. Methods: An analysis of archival and printed sources, literature on the subject and memoirs. Results: On the basis of the research results, the following periods of the Professor’s life are presented: childhood, primary school, secondary school, pedagogical studies at the Catholic University of Lublin, work at managerial positions in higher schools (UMCS, WSPS (APS) and the course of his scientific career. Conclusions: Prof. Dr. Karol Poznanski was an outstanding and well-known historian of upbringing. The analysis of his scientific output allows us to state that his research covered the history of Polish education from the Commission of National Education to the 1860s. His publications are of great cognitive value, as they are based on the results of his own research conducted in the Polish and Russian archives (Leningrad, Moscow). His particular contribution to the development of the Polish history of education are the extensive volumes of sources on the history of education in the Kingdom of Poland in the years 1815–1867. They are an invaluable source for researchers in this field, especially as they contain currently inaccessible materials stored in Russian archives. He also made a significant contribution to the training of young academics by, among other things, socially running a doctoral seminar.
