Sergei Diaghilev

Sergei Pavlovich Diaghilev (also known as Serge), (Russia, 31 March 1872 – 19 August 1929) was a Russian art critic, patron and ballet impresario. He formed a ballet company called "Les Ballets Russes de Serge Diaghilev". Many think it was the greatest ballet company of all time.
For twenty years, between 1909 and 1929, they were the most famous ballet company in the world. Many of their ideas influenced art and music as well as dance. Diaghilev got some of the world's greatest painters to design sets for his productions, and some great composers, including Igor Stravinsky, to compose music for the ballets.
His dancers included the legendary Nijinsky and the Imperial prima ballerina Karsavina; also Pavlova, Danilova and Spessivtseva. His choreographers included Fokine, Nijinska, Massine and Balanchine; his composers included Stravinsky, Rimsky-Korsakov, Prokofiev, Ravel and Debussy; his set designers included Picasso, Cezanne, Matisse, Utrillo, Bakst and Braque; Cocteau worked as an artist and wrote scenarios. The ballets created and the performances changed the course of ballet history.
Diaghilev's gift lay in spotting talent, and bringing great artists to work together. He also persuaded patrons to support the "Ballets Russes". The production costs were enormous, and were not always covered by the ticket prices. The repertoire (list) of new ballets and new music grew, and the productions were not always successful. Diaghilev's company folded soon after his death, though many of the group worked together in new companies.
Diaghilev was homosexual. He died of diabetes.
