Juntwait died Wednesday at age 58 of complications from ovarian cancer, according to NPR.
Juntwait was trained as a lyric soprano at the Manhattan School of Music. But in 1991 — with no radio experience — she wrote a fan letter to WNYC host John Schaefer, who promptly hired her as an assistant. She went on to host two music programs on the station.
In 2004 she became the first woman to host the Met's Saturday broadcasts. That same year, she was diagnosed with ovarian cancer, but continued to host the Met broadcasts for a decade. Her last broadcast was New Year's Eve.
