Henrik Johan Ibsen 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.
