Fredrik Pacius (, ); in German and in Estonian Friedrich Pacius; 19 March 1809 – 8 January 1891) was a German composer, violinist and conductor who lived most of his life in Finland. He is regarded as the "Father of Finnish music".
Pacius was born in Hamburg. He was appointed music teacher at the University of Helsinki in 1834, where he founded a musical society, the student choir Akademiska Sångföreningen and an orchestra, building up orchestral and choral life in the city. In 1848, Pacius set to music the poem "" by Johan Ludvig Runeberg, which became Finland's national anthem. The same melody was also used for the Estonian national anthem "Mu isamaa, mu õnn ja rõõm" and the Livonian ethnic anthem "Min izāmō, min sindimō". In 1852, he composed Kung Carls jagt (English: King Charles' Hunt; Finnish: Kaarle-kuninkaan metsästys), the first opera written in Finland, with a libretto by Zacharias Topelius.
Biography
Early life and training
Pacius grew up in a musical family in Hamburg; his father, the wine merchant Johann Conrad Ludwig Pacius, played violin and hosted weekly string quartet evenings at home. On the recommendation of Hamburg's music director Albert Gottlieb Methfessel, the celebrated violin pedagogue Ludwig Spohr accepted the 15-year-old Pacius as his pupil in Kassel in 1824, where he studied until 1826. Alongside his violin studies, Pacius studied music theory, counterpoint and composition under Moritz Hauptmann.
