Legendary for both their conducting and managerial skills, the two leaders established a formidable institution that is internationally recognized as one of the top opera companies in the world—heralded for its first-rate productions and roster of international opera stars. Following Adler’s tenure, the Company was headed by three visionary leaders: Terence A. McEwen (1982–1988), Lotfi Mansouri (1988–2001), and Pamela Rosenberg (2001–2005). Originally presented over two weeks, the Company’s season now contains approximately seventy-five performances of ten operas between September and July. San Francisco Opera celebrated the 75th anniversary of its performing home, the War Memorial Opera House, in 2007 . The venerable beaux arts building was inaugurated on October 15, 1932 and holds the distinction of being the first American opera house that was not built by and for a small group of wealthy patrons; the funding came thanks to a group of private citizens who encouraged thousands of San Franciscans to subscribe. The War Memorial currently welcomes some 500,000 patrons annually.
