Willem Mengelberg
In 1922, while still a women's group (as it remained until 1965), the Chorus won significant attention when it appeared with The Philharmonic Society of New York under Willem Mengelberg in the first New York performance of Mahler's Symphony No. 3. During this period, the Chorus gave several dozen world and U.S. premieres, by composers including Amy Beach, Deems Taylor, and Virgil Thomson.
