He was born at Tambow, Russia, was a student of physics and mathematics at the University of Moscow until 1901, and from 1901 until 1908 worked in Ostwald's Institute at Leipzig, in which he was appointed assistant in 1906. Returning to Moscow, he became professor in 1916, but lost his position, his property, and very nearly his life in the Russian revolution. After a year as director of the scientific laboratory of the "Agfa"Company (Berlin), he became in 1920 a professor at Zagreb. For his discovery of 'infra-red shadow photography' he received the 'Goldene Verdienstsmedaille' of the Vienna Photographic Society.
