The article analyzes a collection of minerals and rocks compiled in 1911 in Yekaterinburg city in the mineralogical workshop of the Commission for the Dissemination of Natural Science Knowledge of the Ural Society of Natural Science Lovers, stored in the Museum of Scientific Heritage (Ulan-Ude city). It includes both material (stone samples) and written sources (handwritten and printed). It contains information on the history of science, education and museum work in our country in the first decades of the 20th century. The collection was compiled according to J.D. Dana’s mineralogical systematics, typical for museum practice of that period. Its geography covers mainly the Southern Urals, but individual samples were collected in other regions of the Russian Empire.
The collection box contains its catalog, as well as scraps of the newspaper “Russkoye Slovo” and a fragment of a note of 1911, confirming the dating of the collection. The autograph on the catalogue belongs to Nadezhda O. Sharakshinova, a famous folklorist, through whose family the collection came to Buryatia. A second autograph was presumably left by the Yekaterinburg merchant Pyotr I. Yarinsky (~1868–?).
The educational mineral collections of the Ural Society of Natural Science Lovers were in demand by educational institutions across the country in the first decades of the 20th century. This activity is presented in sufficient detail in archival documents and research works. However, very few such educational aids have survived in museum collections. For the Museum of Scientific Heritage, the collection is an opportunity to expand the mineral diversity and geography of its collection; a document that stands out for its historical, scientific and memorial value.

The paper traces in stages the key trends and events in the history of the complex of scientific and educational areas which originated and developed in the Saratov Volga region largely due to the activities of V.I. Vernadsky’s students and followers. On the example of the most outstanding personalities, the influence of such personalities on features of the evolutionary dynamics of specific organizations, the city and the region is shown. Such an analysis allows us to see interregional interactions from a new perspective, the role of the region for the country, as well as to propose original scientific and educational projects for further study and popularization of V.I. Vernadsky’s heritage.
