Leonard Katzman

MALIBU, Calif. (AP) _ Leonard Katzman, executive producer of the Texas oil family saga ``Dallas'' and director of other shows spanning the Golden Age of television to the present, died Thursday from an apparent heart attack. He was 69.

``Dallas'' premiered in 1978 and ran through May 1991, entertaining a worldwide audience with tales of lust and treachery amid oil rigs and sprawling cattle ranches. The ``Who Shot J.R.?'' episode on Nov. 21, 1980, was the most-watched single show in TV history until the final episode of ``MASH'' on Feb. 28, 1983.

Katzman had worked on hit shows for 20 years, with credits including ``Gunsmoke,'' ``The Wild, Wild West'' and ``Hawaii Five-O.''

Katzman produced 356 episodes of ``Dallas,'' also writing and directing a third of them. His three children wrote, acted and directed alongside him. He had recently finished a ``Dallas'' reunion movie to air this fall.
