Ibsen began writing An Enemy of the People before he started Ghosts, but it wasn't completed until after the latter. This play serves as a fierce critique of societal norms, depicting a doctor who exposes the contamination of a town's water supply. Initially hailed as a hero, he becomes a pariah when his discovery threatens the local economy. Viking Press released a 1987 edition of this play, edited by Arthur Miller, the renowned author of Death of a Salesman.

While Ibsen was active in Norway, August Strindberg emerged as Sweden's leading playwright. Both writers delved into new realistic forms. Strindberg's 1888 drama, Miss Julie, which explores the relationship between an aristocratic girl and her manipulative butler, is often regarded as his finest work.

Anton Chekhov, a Russian writer, is celebrated as one of history's greatest short story and drama authors. He cited Ibsen as a significant influence. All of Chekhov's plays are notable, but The Cherry Orchard (1904) particularly explores themes similar to those in Ghosts.

George Bernard Shaw, an Irish playwright, supported moderate Socialist ideas. His political analysis of Ibsen is detailed in his book, The Quintessence of Ibsenism, which is available in a 1994 Dover Books edition.

Ibsen’s life and thoughts are vividly captured in the 1970 publication, Correspondence of Henrik Ibsen, edited by Mary Morrison.

Susan Sontag’s classic essay, Illness as a Metaphor, examines how writers address physical ailments, such as Ibsen’s use of syphilis to symbolize generational decadence. This essay, along with its sequel, AIDS and Its Metaphors, is available in a single volume published in 1995.

Stella Adler, one of America's most influential acting teachers, played a crucial role in training actors like Marlon Brando, Robert DeNiro, and Al Pacino. In 1999, Barry Paris compiled a series of her lectures into the book Stella Adler on Ibsen, Strindberg, and Chekhov.
