Actress Jane Wyatt, the prototypical housewife and mother in the television series "Father Knows Best," has died at age 96, her spokeswoman told CNN Sunday. Wyatt died Friday of natural causes in her sleep at her house in Bel Air, California, said Meg McDonald, Wyatt's goddaughter and publicist.A spokesman for Gates Kingsley & Gates Funeral Home in Santa Monica confirmed the death. Before taking her role in the television series, Wyatt had already established herself as a television pioneer, serving as host of the "Bell Telephone Hour." But it was her co-starring role with Robert Young on "Father Knows Best" that catapulted her to stardom and led her to become the first consecutive winner of the Academy of Television Arts & Sciences' Emmy Award.In the late 1960s, she appeared in an episode of "Star Trek" as Spock's mother, a role she reprised in 1986 in "The Voyage Home," a Star Trek movie.
