The Vienna Chamber Orchestra (Wiener Kammerorchester) was founded in 1946. Philippe Entremont was its chief conductor between 1976 and 1991, and as lifetime honorary conductor, he continues to lead the orchestra on tours and in its subscription concerts at the Vienna Konzerthaus. His appearances as both conductor and soloist have started a tradition, as the orchestra has frequently invited such artists as Yehudi Menuhin, Heinz Holliger, and Heinrich Schiff to collaborate in a dual role. The tradition was maintained by Ernst Kovacic, who succeeded Entremont as chief conductor from 1996 to 1998. In October 1999 the orchestra gave nine concerts throughout the United States, and it toured there again in 2002. In 1999 Christoph Eberle assumed the position of chief conductor.
