Due to the mother's revolutionary activity Nikolay was raised by relatives. He became a known writer in early 20th century. In 1920, after the Russian Revolution (1917), he emigrated to Warsaw, Poland, but was expelled in 1927 because of conflict with the Sanacja régime. He became a French citizen.
