In the years 1904–1908, he studied chemistry, physics, and mathematics at the Lwów University, where his professors included Wacław Sierpiński, Marian Smoluchowski, Stanisław Tołłoczko, Kazimierz Twardowski and Leonard Bronisław Radziszewski.^[3] In years 1908 - 1909, under a scholarship, he worked with Fritz Haber in Karlsruhe, i.a., on the potential of the glass electrode. In 1912, he passed his habilitation degree at Lwów. In the years 1913 - 1914, he worked with Marie Skłodowska-Curie in Paris, i.a., on the electrochemical properties of radium-B and thorium-B.^[4] During the WWI, he worked at first as a professor at the Pasteur Institute, and then in a plant manufacturing Solvarsan. In 1920 - 1940, he was an ordinary professor of physics and electronics at the Lwów Polytechnic. In years 1940 to 1942, he was in Kazakhstan (deported), then Iran, Egypt, and Great Britain (1944 until 1956). From 1956, he was a professor at the Silesian University of Technology in Gliwice.^[5]
