In Henrik Ibsen's play "A Doll's House," Torvald Helmer is the husband of the protagonist, Nora. Torvald is portrayed as a traditional, authoritative husband who values societal norms and appearances. His role in the play is to exemplify the patriarchal society of the time and its impact on Nora's personal growth and self-discovery. Through Torvald's patronizing and controlling behavior, Ibsen highlights the limitations and oppression faced by women in 19th-century society.
