Louis Glass (1864–1936) was a Danish composer and conductor, primarily associated with classical music. He is known for his contributions to symphonic and chamber music, as well as choral works. Notable works by Glass include his symphonies, string quartets, and the opera "Klodskhed," which reflects his interest in blending traditional forms with contemporary influences. He also composed a significant amount of music for piano and various vocal ensembles. Glass was part of the late Romantic movement and contributed to the development of Danish national music.
