Mikhail Mikhailovich Ippolitov-Ivanov (Russian: Михаи́л Миха́йлович Ипполи́тов-Ива́нов; 19 November [O.S. 7 November] 1859 – 28 January 1935) was a Russian composer, conductor and teacher.
He was born in 1859 at Gatchina, near St. Petersburg, where his father was a mechanic employed at the palace. His birth name was Mikhail Mikhailovich Ivanov; later he added Ippolitov, his mother's maiden name, to distinguish himself from a music critic with a similar surname. He studied music at home and was a choirboy at the cathedral of St. Isaac, where he also had musical instruction, before entering the St. Petersburg Conservatory in 1875. In 1882 he completed his studies as a composition pupil of Rimsky-Korsakov, whose influence was to remain strong.
Ippolitov-Ivanov's first appointment was to the position of director of the music academy and conductor of the orchestra in Tbilisi (Tiflis), the principal city of Georgia, where he was to spend the next seven years. This period allowed him to develop an interest in the music of the region, a reflection of the general interest taken in the music of non-Slav minorities and more exotic neighbours that was current at the time, and that was to receive overt official encouragement for other reasons after the Revolution. One of his notable pupils in Tbilisi was conductor Edouard Grikurov.
On 1 May 1886, in Tbilisi, he conducted the premiere of the third and final version of Tchaikovsky's Romeo and Juliet Overture-Fantasia.
In 1893 Ippolitov-Ivanov became a professor at the Conservatory in Moscow, of which he was director from 1905 until 1924. He served as conductor for the Russian Choral Society, the Mamontov and Zimin Opera companies and, after 1925, the Bolshoi Theatre, and was known as a contributor to broadcasting and to musical journalism.
