Question: Who designed the Moscow theatre where the original production of Swan Lake was kept in the active repertoire?
Sentence (from "Julius Reisinger"): His work on "Swan Lake" was considered unsuccessful by the critics of the day but not necessarily unsuccessful by the theatre-going public—after all, Reisinger's original production of "Swan Lake" was kept in the active repertoire of the Bolshoi Theatre for seven years and was performed over thirty times during a period when other ballets could not sustain even twenty performances.
Relevant evidence: Yes
