Expeditions of the Russian Geographical Society have always consisted of tremendous work on collection of cartographic and meteorological data, ethnographic, geological, botanical collections. In addition, any expedition was accompanied by a daily and detailed recording of everything that happened to scientists and travelers. They kept diaries and drew maps, sketched new species of plants and animals themselves or asked an artist accompanying the expedition to do it, photographed settlements and landscapes encountered along the way, described in detail the customs of the life of local residents. All these documents eventually made up the stock collection of the Russian Geographical Society, the formation of which began from the moment of its establishment in 1845. In our online exhibition, we will show only a small part of this rich and interesting collection and tell about nineteen researchers.
