Willowy brunette actress Kate Jackson spent her early adulthood in summer stock, in training at the American Academy of Dramatic Arts, and as a page and tour guide at the NBC studios in Rockefeller Center. Anxious to burst forth with reams of dialogue as a film and TV actress, Jackson found herself in the utterly non-speaking role of a glamorous ghost on the mid-1960s daytime TV serial Dark Shadows. She was allowed to flap her gums a little more often as Jill Danko on TV's The Rookies (1973-76). Full stardom arrived for Jackson when she was cast as Sabrina Duncan, "the smart one" on the prime time jigglefest Charlie's Angels; she remained with this series from 1976 through 1979. Her last regular weekly TV effort was Scarecrow and Mrs. King (1983-1987) in which she played an average housewife who moonlighted as a secret agent. Though Jackson has made sporadic film appearances, it is safe to say that her greater fame rests upon her small-screen work. Jackson received an outpouring of industry sympathy and support when she battled breast cancer in the early 1990s. In recent years, Kate Jackson has been a prolific and popular TV commercial spokesperson.
