Frances Bible: Frances Lillian Bible (January 26, 1919 – January 29, 2001) was an American operatic mezzo-soprano who had a thirty-year-long career at the New York City Opera between 1948 and 1978.  She also made a fair number of opera appearances with other companies throughout the United States, but only made a limited number of appearances abroad.  Martin Bernheimer wrote in "Opera News" that, "Frances Bible was cheated by destiny.  She never quite achieved the international recognition she deserved.  Bible had it all—a mellow, wide-ranging mezzo-soprano, an attractive stage presence, genuine theatrical flair, a probing mind and a technique that allowed her to sing bel-canto filigree one night, Verdian drama the next.  She was one of the rare American singers who savor the English language.  She understood the value of economy, never stooping to easy effects.  Perhaps she was too versatile, too tasteful and — dare one say it?  — too intelligent for her own good."
