"Marni Nixon, the American cinema’s most unsung singer, died on Sunday in Manhattan. She was 86."
"The cause was breast cancer, said Randy Banner, a student and friend. Ms. Nixon, a California native, had lived in Manhattan, on the Upper West Side, for more than 40 years."
"Classically trained, Ms. Nixon was throughout the 1950s and ’60s the unseen — and usually uncredited — singing voice of the stars in a spate of celebrated Hollywood films. She dubbed Deborah Kerr in “The King and I,” Natalie Wood in “West Side Story” and Audrey Hepburn in “My Fair Lady,” among many others."
