The article is devoted to the study of the scientific and teaching activities of Kadyr and Maryam Gubaidullins, who were actively engaged in the study of the history and ethnography of the Tatars in the 1920s. The contribution of young ethnographers to the development of Tatar ethnography for a number of reasons did not become the object of special research. Based on archival documents from the collections of the Central Museum of the Tatar Republic, the North-Eastern Archaeological and Ethnographic Institute, the Eastern Pedagogical Institute and the memoirs of relatives, the article presents in more detail the scientific and teaching activities of Kadyr and Maryam Gubaidullins. It is concluded that they were at the origins of the organization of higher special ethnographic education in the republic, carried out significant work on the collection and popularization of field ethnographic materials. Most of their works were the first studies in the Tatar national ethnography of the 1920s and served as the basis for further research.
