Yuri Alexandrovich Shaporin (Russian: Юрий (Георгий) Александрович Шапорин) (8 November [O.S. 27 October] 1887 – 9 December 1966), PAU, was a Soviet composer.
After the Bolshoi Drama Theater was established in 1919, he served as its musical director until 1928. He then worked with the Russian State Pushkin Academy Drama Theater — also known as the Alexandrinsky Theater — until 1934. During this period he composed a significant amount of theater music. He was a founding member of the Association for Contemporary Music in 1923.
During the 1930s Shaporin turned his attention to large scale works. His opera Dekabristi (The Decembrists), to a libretto written by Aleksey Nikolayevich Tolstoy about the Decembrist revolt, had been on Shaporin's mind since 1920 — a 1925 interim version, Polina Gyobe, had two scenes staged in Leningrad (as it had been renamed in 1924). In 1938, Shaporin received an offer of a teaching position at the Moscow Conservatory and he moved to Moscow.
That year, he completed a version of Dekabristi for a commission by the Bolshoi Theatre, but dissatisfied with it, he decided to revise it. In 1952, Shaporin was awarded the Stalin Prize. The opera was only completed in 1953, after collaboration with librettist Vsevolod Rozhdestvensky, and it was premiered at the Bolshoi Theatre on 23 June 1953.
