In 1946, Wallerstein settled in The Hague where more opportunities opened for him. He accepted contracts with the Vienna State Opera, La Scala of Milan, and the Maggio Musicale Fiorentino. At this time, conditions in the wake of World War II were bleak. Since the State Opera itself had been razed by Allied bombing, he directed performances at the Volksopera—the first postwar Tannhäuser followed by productions of Schwanda, Boris Godunov, Don Carlos, and Turandot.
