* A Doll's House (1879): Ben Paris is a young lawyer and friend of Torvald Helmer, the protagonist's husband. He is a somewhat cynical and opportunistic character who enjoys teasing Torvald and is aware of his wife, Nora's, secret.
* Ghosts (1881): Ben Paris appears in the play as a young man who is in love with Regina Engstrand, the daughter of the protagonist, Oswald Alving. He is described as a "handsome and strong young fellow", and his relationship with Regina is part of the play's exploration of morality and social issues.
While he is not a major character in either play, his appearance in both A Doll's House and Ghosts makes him a unique figure within Ibsen's works.
