Ignacy Feliks Dobrzyński
Ignacy Feliks Dobrzyński (15 February 1807 – 9 October 1867) was a Polish pianist and composer. He was the son of Ignacy Dobrzyński, the brother of Edward Dobrzyński, and the father of Bronisław Dobrzyński.
He first studied music with his father Ignacy, a violinist, composer and music director. Beginning in 1825 he studied in Warsaw with Józef Elsner, at first privately, then in 1826–28 at the Warsaw Conservatory, where he was a classmate of Frédéric Chopin.
In 1835, he won second prize in a composition competition for his Symphony No. 2 in C Minor, Op. 15. This symphony was later called "Symphony in the Characteristic Spirit of Polish Music" and movements were conducted by Felix Mendelssohn. In 1845 Dobrzyński toured Germany as a soloist and also conducted operas and concerts.
In 1857 he founded "Ignacy Feliks Dobrzyński's Polish Orchestra" (Orkiestra Polska Ignacego Feliksa Dobrzyńskiego), which comprised leading members of the orchestra of Warsaw's Grand Theatre. In 1858–60 he participated in a committee established to found a Music Institute. He also became a member of the Lwów Music Society.
He died in Warsaw on October 9, 1867, at the age of 60.
