Rebecca luker cause of death: Rebecca Luker, the entertainer and artist who in a commended three-decade vocation on the New York stage exemplified the quintessence of the Broadway melodic ingénue in hit recoveries of “Show-off,” “The Sound of Music” and “The Music Man,” kicked the bucket on Wednesday in a medical clinic in Manhattan. She was 59.

The passing was affirmed by Sarah Fargo, her representative. Ms. Luker declared in February that she had amyotrophic horizontal sclerosis, regularly known as A.L.S. or on the other hand Lou Gehrig’s sickness.

Ms. Luker’s Broadway vocation, filled by her completely clear operatic soprano, brought her three Tony Award assignments. The previously was for “Show-off” (1994), in which she played Magnolia, the chief’s dewy-new high school girl, whose life is demolished by union with a riverboat card shark. The second was for “The Music Man” (2000), in which she was Marian, the demure River City bookkeeper who captivates a voyaging nonsense man who thinks — erroneously — that he’s simply going through town.
