David Dortort

David Dortort (born David Solomon Katz; October 23, 1916 – September 5, 2010) was a Hollywood screenwriter and producer, widely known for his role as producer in two successful NBC television series: Bonanza (1959–73) and The High Chaparral (1967–71).

Dortort published two books, Burial of the Fruit in 1947 and The Post of Honor in 1949.

From 1954–55, Dortort was involved in directing and writing for The Public Defender.

He produced The Restless Gun (1957–59), The Cowboys television version (1974), and a prequel series featuring younger versions of the Bonanza characters called Ponderosa (2001), which was produced with Beth Sullivan.

Michael Landon appeared in a supporting role in the pilot for The Restless Gun, starring John Payne, aired on March 19, 1957, as an episode of The Schlitz Playhouse of Stars and Dan Blocker played multiple roles in five episodes of The Restless Gun.

Alan W. Livingston of NBC hired Dortort to write the screenplay for the pilot episode of Bonanza.

He did it at night, while producing The Restless Gun by day.

Dortort's focus shifted in the late 1960s to the newer series, leaving the production of Bonanza largely to his associates during its last five and a half years (1967–1973).

In 1979–1980, he created the 13-week CBS miniseries, The Chisholms.

In 2001, the alumni association of City College of New York, where he had studied history, honored him with its John H. Finley award.

A native of New York City, Dortort was married for 67 years to the former Rose Seldin, who died September 30, 2007, at age 92.

They had two children, Wendy Dortort Czarnecki and Fred Dortort.

Dortort died in his sleep at his home in Los Angeles, California, on September 5, 2010, a month and a half before his 94th birthday, following a history of heart disease.
