DIAGHILEV, SERGEI PAVLOVICH Russian ballet producer, was born in the province of Novgorod, Russia, March 19, 1872. Af ter studying law and music he organ ized art exhibitions in St. Petersburg (Leningrad). In 1899 he founded the review Mir Iskusstra (The World of Art), to which Somov and Bakst contributed, and which exercised a powerful influence on Russian art. From 1907 onwards he occupied him self with musical and theatrical productions and organized a num ber of Russian concerts in Paris; there he produced in 1908 and 1909 Russian operas (Boris Godunov and The Maid of Pskof) and ballets. Subsequently he organized successful ballet and opera seasons in London, Paris, Berlin, America and elsewhere. One of his most successful operatic productions was that of Moussorg sky's Khovanshtchina. In England the originality of his concep tions may be said to have effected a revolution in choreographic art, and further put new life into stage dancing, which by the end of the 19th century had degenerated into a spectacular show of little artistic significance. Among his numerous successful bal lets may be mentioned: Carnaval (music by Schumann), Scite herazade (music by Rimsky-Korsakov), Petrouschka (music by Stravinsky), La Boutique Fantasque (music by Rossini) and The Three Cornered Hat (music by de Falla)—to name but a few of a very large number. In 1904 M. Diaghilev produced a valuable book on the painter Levitsky. A collection of photographs and drawings illustrating the ballet, Les Biches, was published in 1924 by B. Koshno. (See also BALLET.) He died at Lido, Aug. 19, 1929.
