Context: Mussorgsky (Russian: Мусоргский , "Musorgskiy " ) is a 1950 Soviet biopic film directed by Grigori Roshal, about the emergence of Russian composer Modest Mussorgsky.  It was entered into the 1951 Cannes Film Festival. Mikhail Ivanovich Chulaki (Russian: Михаи́л Ива́нович Чула́ки, also transliterated as Tchulaki and Tschulaki ) (November 19 [O.S. November 6] 1908 , Simferopol – January 29, 1989, Moscow) was a Soviet Russian composer and teacher. Tchaikovsky (Russian: Чайковский ) is a 1970 Soviet biopic film directed by Igor Talankin.  It featured Innokenty Smoktunovsky in the role of the famous Russian composer Pyotr Ilyich Tchaikovsky.  It was nominated for the 1971 Academy Award for Best Foreign Language Film as well as the Academy Award for Original Song Score and Adaptation. Mikhail Ivanovich Alafusov (1891 – July 13, 1937) was a Soviet general who received the title of Komkor on November 11, 1935.  He was born in Mykolaiv in what it is now Ukraine.  He was a recipient of the Order of St. Anna and the Order of Saint Stanislaus (Russian) from the Russian Empire and the Order of the Red Banner from the Soviet Union.  He fought in World War I in the Imperial Russian Army and in the Russian Civil War in the Soviet Red Army.  During the Great Purge, he was arrested on April 15, 1937 and later executed in Moscow.  He was on the death list of July 10, 1937, which was signed by Joseph Stalin and Vyacheslav Molotov. The Glinka Islands are a small group of rocky islands in Lazarev Bay, Antarctica, immediately east of Rothschild Island.  They were first photographed from the air by the United States Antarctic Service, 1939–41, and were mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960.  They were named by the UK Antarctic Place-Names Committee for Mikhail Ivanovich Glinka, the Russian composer. Kamarinskaya (Russian: камаринская ) is a Russian traditional folk dance, which is mostly known today as the Russian composer Mikhail Glinka's composition of the same name.  Glinka's "Kamarinskaya", written in 1848, was the first orchestral work based entirely on Russian folk song and to use the compositional principles of that genre to dictate the form of the music.  It became a touchstone for the following generation of Russian composers ranging from the Western-oriented Pyotr Ilyich Tchaikovsky to the group of nationalists known collectively as The Five and was also lauded abroad, most notably by French composer Hector Berlioz. Mily Alexeyevich Balakirev (Russian: Ми́лий Алексе́евич Бала́кирев , ] ; 2 January 1837  – 29 May [O.S. 16 May] 1910 ) was a Russian pianist, conductor and composer known today primarily for his work promoting musical nationalism and his encouragement of more famous Russian composers, notably Pyotr Ilyich Tchaikovsky.  He began his career as a pivotal figure, extending the fusion of traditional folk music and experimental classical music practices begun by composer Mikhail Glinka.  In the process, Balakirev developed musical patterns that could express overt nationalistic feeling.  After a nervous breakdown and consequential sabbatical, he returned to classical music but did not wield the same level of influence as before. Mikhail Ivanovich Glinka (Russian: Михаи́л Ива́нович Гли́нка ; 1 June [O.S. 20 May] 1804 15 February [O.S. 3 February] 1857 ) was the first Russian composer to gain wide recognition within his own country, and is often regarded as the fountainhead of Russian classical music.  Glinka's compositions were an important influence on future Russian composers, notably the members of The Five, who took Glinka's lead and produced a distinctive Russian style of music. Pirogov (Russian: Пирогов ) is a 1947 Soviet biopic film directed by Grigori Kozintsev, based on the life of Russian scientist and doctor Nikolay Ivanovich Pirogov (1810-1881).
