"Mary Rodgers Guettel was a gifted author and composer; adding to her family's achievements of musical theatre greatness," said Charlotte St. Martin, executive director of the Broadway League, in a statement. "The lights of Broadway are being dimmed in honor of someone who was a muse and inspiration to so many, and she will be missed. Our thoughts are with her friends and family." Ms. Rodgers grew up in a household steeped in music and theatre culture. She was born Jan. 11, 1931, to Richard Rodgers and his wife Dorothy Bell Feiner Rodgers. When still in her 20s, she wrote, with lyricist Marshall Barer and bookwriters Jay Thompson and Dean Fuller, Once Upon a Mattress, a musical adaptation of the Hans Christian Anderson fable "The Princess and the Pea." The musical later arrived on Broadway in 1959 and made a star out of its lead actress, Carol Burnett, who made comic hay out of the awkward Princess Winnifred. Burnett and the musical received Tony nominations.
