David Dortort, born 1916, is a Hollywood producer and writer, best known for his role as producer in the television series Bonanza (1959-1967) and The High Chaparral (1967-1971). Much of Dortort's energies in the late 1960's went to the newer series, therefore leaving the production of Bonanza mostly to his associates during its last five and a half years (1967-73).
Other series produced by Dortort were The Restless Gun, The Cowboys (1974), and a prequel series featuring younger versions of the Bonanza characters called Ponderosa (2001), which was produced with Beth Sullivan. In 1979-1980, he created the 13-week CBS miniseries, The Chisholms, starring Robert Preston, Rosemary Harris, and Ben Murphy.
