Bjørnstjerne Martinius Bjørnson was a Norwegian writer who received the 1903 Nobel Prize in Literature 'as a tribute to his noble, magnificent and versatile poetry, which has always been distinguished by both the freshness of its inspiration and the rare purity of its spirit'. Bjørnson is considered to be one of The Four Greats (De Fire Store) among Norwegian writers, the others being Henrik Ibsen, Jonas Lie, and Alexander Kielland. Bjørnson is also celebrated for his lyrics to the Norwegian National Anthem, 'Ja, vi elsker dette landet'.
