Abstract: The subject of this research is the potential of pedagogical pseudonomastics (science on the pseudonyms the participants of pedagogical process) as an instrument of interdisciplinary analysis of pedagogical history of white émigré of the 1920’s – early 1930’s. The object of this research is the system of pseudonyms presented in the émigré publishers dedicated to pedagogy and cognate areas. Leaning on the modern research of pseudonyms of the white émigré, the authors suggest a so-called “pedagogical filter” that allows among the fictitious names identifying those belonging to prominent pedagogues and find out the scope of works published by them. The scientific novelty consists in the fact that the authors are first to formulate the subject and objectives of pedagogical pseudonomastics as a possible instrument for studying pedagogical history of white émigré, and determination of new data complementing biography and bibliography of the Russian pedagogues abroad. The conclusion is made on importance of the factor of fictitious name for specifying the role of author within the émigré pedagogical space, as well as for understanding of editorial policy of those who covered the pedagogical theme of publishers and hierarchy of presented genres therein. The new archival documents, pseudonyms and their attributions are introduced into the scientific discourse.
