However, in 1949, there was only a temporary roof on the Staatsoper, as construction work continued. It was not until 5 November 1955, after the Austrian State Treaty, that the Staatsoper could be reopened with a performance of Beethoven's "Fidelio", conducted by Karl Böhm. The American Secretary of State, John Foster Dulles, was present. The state broadcaster ORF used the occasion to make its first live broadcast, at a time when there were only c. 800 televiewers in the whole of Austria. The new auditorium had a reduced capacity of about 2,276, including 567 standing room places. The ensemble, which had remained unified until the opening, crumbled in the following years, and slowly an international ensemble formed.
