Chicago Symphony Orchestra
The Chicago Symphony Orchestra, based in Chicago, Illinois, is one of the major orchestras in the United States.It played its first concert on October 16, 1891 conducted by Theodore Thomas, making it the third oldest symphony orchestra in the United States (behind the New York Philharmonic and the Saint Louis Symphony Orchestra). At that time it was known simply as the Chicago Orchestra, before changing its name to the Theodore Thomas Orchestra in 1906, and taking its present name in 1912.
