Alexander Konstantinovich Glazunov (Russian: Александр Константинович Глазунов, Aleksandr Konstantinovič Glazunov; French: Glazounov; German: Glasunow; August 10, 1865 ? March 21, 1936) was a major Russian composer, as well as an influential music teacher.
Glazunov was born in St Petersburg. He studied music under Nikolai Rimsky-Korsakov.
The first of his 9 symphonies premiered in 1882 when Glazunov was 16 years old. His popular Stenka Razin was also a youthful work. Glazunov also wrote 3 ballets.
In 1899, Glazunov became a professor at the St Petersburg School of Music, and later its director. Glazunov left Russia in 1928. He toured Europe and the United States, and died in Paris.
He came to be acknowledged as a great prodigy in his field, and with the help of his mentor and friend Rimsky-Korsakov, finished some of Alexander Borodin's great works, the most famous being the opera Prince Igor, including the popular Polovetsian Dances.
