Thorvald Lammers (1841, Modum – 1922) was a Norwegian baritone singer, conductor, composer and biographer. He made his song début in Oslo in 1873. He founded the choir known as Korforeningen in 1879, and conducted it until 1909.[1] Around 1900, Lammers was regarded as Norway's most important male singer. Among his compositions are the songs "Gamle Norig" and "Der ligger et land".[2]
