Los Angeles ? Barbara Bel Geddes, the winsome actress who rose to stage and movie stardom but reached her greatest fame as Miss Ellie Ewing in the long-running TV series “Dallas,” has died. She was 82.

The San Francisco Chronicle said she died Monday of lung cancer at her home in Northeast Harbor, Maine.

Bel Geddes, daughter of renowned industrial designer Norman Bel Geddes, was nominated for an Academy Award for best supporting actress for the 1948 drama “I Remember Mama” and was the original Maggie the Cat on Broadway in “Cat on a Hot Tin Roof.”

“Dallas” came late in her career. She had retired to take care of her husband, Windsor Lewis, after he fell ill with cancer in 1966. He died in 1972.

Her earnings depleted by his long illness, she found work scarce for a middle-aged actress and said she was “flat broke” in 1978 when she accepted the role as matriarch of a rambunctious Texas oil family.

Though castigated by critics, “Dallas” hurtled to the top of the audience ratings and spawned copycat shows. Bel Geddes won an Emmy in 1980 as best lead actress in a drama series and remains the only nighttime soap star to be so honored.

Bel Geddes called “Dallas “real fun,” but it was also marked by tragedy. In 1981, Jim Davis, who played Miss Ellie’s husband, Jock Ewing, died.

In March 1984, Bel Geddes was stricken with a major heart attack. Miss Ellie was played by Donna Reed for six months, then Bel Geddes returned to “Dallas,” remaining until 1990, a year before CBS canceled the show.

In 1945, Bel Geddes made a splash on Broadway at 23 with her first important role in “Deep Are the Roots,” winning the New York Drama Critics Award as best actress.

She announced to a reporter: “My ambition is to be a good screen actress. I think it would be much more exciting to work for Frank Capra, George Cukor, Alfred Hitchcock or Elia Kazan than to stay on Broadway.”

Hollywood was quick to notice. In 1946 she signed a contract with RKO.

But after four movies, Howard Hughes, who had bought control of RKO in 1948, dropped her contract because “she wasn’t sexy enough.”

Bel Geddes was devastated. But it turned out to be a good happenstance. She had time to return to the stage, and she scored a triumph in 1955 as Maggie the Cat in Tennessee Williams’ “Cat on a Hot Tin Roof.”
