Henrik Johan Ibsen (20 March 1828 - 23 May 1906) was a major 19th-century Norwegian playwright, theatre director, and poet. He is often referred to as "the father of realism" and is one of the founders of Modernism in theatre. His major works include Brand, Peer Gynt, An Enemy of the People, Emperor and Galilean, A Doll’s House, Hedda Gabler, Ghosts, The Wild Duck, Rosmersholm, and The Master Builder. He is the most frequently performed dramatist in the world after Shakespeare, and A Doll’s House became the world’s most performed play by the early 20th century. Several of his plays were considered scandalous to many of his era, when European theatre was required to model strict morals of family life and propriety. Ibsen’s work examined the realities that lay behind many facades, revealing much that was disquieting to many contemporaries. It utilized a critical eye and free inquiry into the conditions of life and issues of morality. The poetic and cinematic play Peer Gynt, however, has strong surreal elements."
