Tom Stoppard constructs a world that was lost to history in “Leopoldstadt” about the Merz-Jacobovitch family of wealthy, assimilated Jews in early 20th century Vienna. “Leopoldstadt” opens the Huntington Theatre’s 2024–25 season on Sept. 17th and will run until Oct. 12. Directed by Carey Perloff, the play covers 50 years of family history as their world is torn apart by the rise of religious, social, and nationalist movements against them in Europe after the Holocaust.
