Before World War I, travelled all over Russia giving tremendously popular lectures on literary subjects. The texts of his lectures were later published in several volumes under the title Siluety Russkikh Pisatelei, giving charming impressionistic vignettes of many Russian literary figures. Understandable to the uninitiated, and somewhat overloaded by quotations, the lectures are by no means without deeper insight (e.g. a realistic appraisal of Gorkii at the time when he was at the peak of his success, or his judgment on Gumilev, when he was still not widely known).
Emigrated after the Bolshevik take-over. Settled in Berlin. Became the main literary critic of the Russian right-of-centre newspaper, Rur.
