César Franck was a Belgian-born composer, pianist, and organist who became a prominent figure in the late Romantic music period. Born on December 10, 1822, he later moved to France, where he spent most of his life. Franck is best known for his symphonic and chamber music, as well as his contributions to organ music, particularly his Six Pièces for organ. Franck's music is characterized by rich harmonies and intricate counterpoint. He served as a professor at the Paris Conservatoire and influenced many younger composers. His most famous works include the Symphony in D minor and the Violin Sonata in A major, which remain popular in concert repertoires today.
