Natives of the Russian Empire in the laboratory of Jaroslav Heyrovský
In the 1920s, due to the First World War and subsequent events in the Soviet Union, many educated and ambitious young people of diferent nationalities were forced to leave the country where they were born. A lot of them ended up in Prague. Thanks to the policy of President Masaryk, students who did not complete their education in the Russian Empire or in the Soviet Union were allowed to continue their studies in Czechoslovakia. In this text, we focus on the laboratory of Nobel Laureate Jaroslav Heyrovský, where 13 students born in the Russian Empire worked in the 1920s and 1930s. At that time, the basics of polarography were developed by the group of Heyrovský, and the frst polarographic articles were published. Documents in the archives of the Czech Republic and the Russian Federation, as well as previously published articles about Heyrovský and his students, made it possible to trace the biographies of natives of the Russian Empire. Their work and life in Prague is a lasting testimony to the humanistic position of Heyrovský and the Czechoslovakian government during a most complicated period of history in Eastern Europe.
