Léon Samoilovitch Bakst (Russian: Лео́н Никола́евич Бакст) (May 10, 1866 – December 28, 1924) was a Russian painter and scene- and costume designer. He was a member of the Sergei Diaghilev circle and the Ballets Russes, for which he designed exotic, richly coloured sets and costumes.
Leon was born in Grodno (currently Belarus) in a middle-class Jewish family. After graduating from gymnasium, he studied at the St. Petersburg Academy of Arts as a noncredit student, working part-time as a book illustrator.
He continued easel painting as well producing portraits of Filipp Malyavin (1899), Vasily Rozanov (1901), Andrei Bely (1905), Zinaida Gippius (1906). He also worked as an art teacher for the children of Grand Duke Vladimir Alexandrovich of Russia. In 1902, he took a commission from Tsar Nicholas II to paint Meeting of Russian sailors in Paris.
In 1898, he showed his works in the Diaghilev-organized First exhibition of Russian and Finnish Artists; in World of Art exhibitions, as well as the Munich Secession, exhibitions of the Union of Russian Artists, etc.
Beginning in 1909, Bakst worked mostly as a stage-designer, designing sets for Greek tragedies, and, in 1908, he made a name for himself as a scene-painter for Diaghilev with the Ballets Russes. He produced scenery for Cleopatra (1909), Scheherazade (1910), Carnaval (1910), Narcisse (1911), Le Spectre de la Rose (1911), and Daphnis et Chloé (1912)). During this time, he lived in western Europe because, as a Jew, he did not have the right to live permanently outside the Pale of Settlement.
During his visits to Saint Petersburg he taught in Zvantseva's school, where one of his students was Marc Chagall (1908–1910).
In 1922, Bakst broke off his relationship with Diaghilev and the Ballets Russes. During this year, he visited Baltimore and, specifically Evergreen House - the residence of his friend and patron, art philanthropist Alice Warder Garrett (1877-1952). Having met in Paris in 1914, when Mrs. Garrett was accompanying her diplomat husband in Europe, Bakst soon depended upon his then new American friend as both a confidante and agent. Alice Garret became Bakst's representative in the United States upon her return home in 1920, organizing two exhibition's of the artist's work at New York's Knoedler Gallery, as well as subsequent traveling shows. When in Baltimore, Bakst re-designed the dining room of Evergreen into a shocking acidic yellow and 'Chinese' red confection. The artist subsequently went on to transform the house's small c. 1885 gymnasium into a colorfully Modernist private theatre, which is currently believed to be the only extant private theatre designed by Bakst.
