Chita Rivera, the fire-and-ice dancer, singer and actress who leapt to stardom in the original Broadway production of “West Side Story” and dazzled audiences for nearly seven decades as a Puerto Rican lodestar of the American musical theater, died on Tuesday. She was 91.

The death was announced in a statement by her daughter, Lisa Mordente. It gave no other details. Ms. Rivera lived in Rockland County, N.Y.

To generations of musical aficionados, Ms. Rivera was a whirling, bounding, high-kicking elemental force of the dance; a seductive singer of smoky ballads and sizzling jazz; and a propulsive actress of vaudevillian energy. She appeared in scores of stage productions in New York and London, logged 100,000 miles on cabaret tours and performed in dozens of films and television programs.

On Broadway, she created a string of memorably hard-edged women — Anita in “West Side Story” (1957), Rosie in “Bye Bye Birdie” (1960), the murderous floozy Velma Kelly in “Chicago” (1975) and the title role in “Kiss of the Spider Woman” (1993). She sang enduring numbers in those roles: “America” in “West Side Story,” “One Boy” and “Spanish Rose” in “Bye Bye Birdie,” and “All That Jazz” in “Chicago.”

Critics thumbed thesauruses for hyperboles to rhapsodize about her pyrotechnics. In 2005, Newsweek called her “only the greatest musical-theater dancer ever.” Reviewing her performance in “Bye Bye Birdie” in The New York Times, Brooks Atkinson called her “a flammable singer and gyroscopic dancer.” Of her Tony Award-winning romp as Anna in “The Rink” (1984), Richard Corliss in Time magazine wrote: “Packing 30 years of Broadway savvy into the frame of a vivacious teenager, the 51-year-old entertainer could by now sell a song to the deaf.”
