The object of the study is the personality of the scientist, the subject is the representation of personality through the analysis of the content of the documents of the Scientific Archive of the Federal Research Center "Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences" introduced into scientific circulation for the first time. The appearance in Syktyvkar of the reporting documents of Shennikov and his young colleagues on geobotanical expeditions of the 1920s-1930s was explained by the evacuation of the Northern Base of the USSR Academy of Sciences from Arkhangelsk to Syktyvkar at the beginning of the Great Patriotic War.
