Henrik Johan Ibsen (20 March 1828 – 23 May 1906) was a Norwegian playwright, theatre director, and poet. As one of the founders of Modernism in theatre, Ibsen is often referred to as "the father of realism" and one of the most influential playwrights of his time. 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, When We Dead Awaken, Pillars of Society, The Lady from the Sea, Rosmersholm, The Master Builder, and John Gabriel Borkman. He is the most frequently performed dramatist in the world after Shakespeare, and by the early 20th century A Doll's House became the world's most performed play.
