Ignacy Feliks , a Polish composer active in Warsaw, is best known for having been a colleague of Frederic Chopin while they were both composition students of Jozef Eisner. As an early nationalist composer, Dobrzynski is examined within the context of nineteenth-century Warsaw's musical culture and political situation. Dobrzynski early training was provided by his father, who was Kapelmeister at the Ilinski court in Romanow. The most important achievements of the career which followed Dobrzynskifs move to Warsaw in 1825 include second place in an 1835 Viennese contest with the Second Symphony, a German tour in I8I8, and the directorship of the Teatr Wielki in 1852. Cast in the late eighteenth-centurv style, Dobrzynski two symphonies were composed in 1829 and 1831. These works show knowledge of Beethoven's music and exhibit Dobrzynski's skill at orchestration. Symphony No. 2 in C minor, Op. 15, is the more important work because of national elements in each movement, as well as its success in a Viennese symphony contest in 1835. Although a precedent for national elements is seen in studying the development of the Polish symphony in the eighteenth and early nineteenth centuries, Dobrzynski's contribution shows an intensification of musical patriotism which was inspired by the November Insurrection of 1830-1831. An edition of the Second Symphony and a list of Dobrzynski's works are included in the dissertation.
