Guided by a fervent strain of idealism, Gregers endeavors to reveal the truth to Hjalmar, and thereby free him from the mendacity which surrounds him. To that end, Gregers takes up residence in the Ekdal Home.
He meddles in the affairs of a strange family, producing disastrous results. Figuratively speaking, he lives in a house whose closets are full of skeletons. Over the course of the play the many secrets that lie behind the Ekdals' apparently happy home are revealed to Gregers, who insists on pursuing the absolute truth, or the "Summons of the Ideal". This family has achieved a tolerable modus vivendi by ignoring the skeletons (among the secrets: Gregers' father may have impregnated his servant Gina then married her off to Hjalmar to legitimize the child, and Hjalmar's father has been disgraced and imprisoned for a crime the elder Werle committed.) and by permitting each member to live in a dreamworld of his own—the feckless father believing himself to be a great inventor, the grandfather dwelling on the past when he was a mighty sportsman, and little Hedvig, the child, centering her emotional life around an attic where a wounded wild duck leads a crippled existence in a make-believe forest.
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.
