He was the writer, director and producer of “The Incredible Machine,” an early National Geographic special that had “extraordinary impact,” said Nicolas Noxon, a documentarian who was Rosten’s longtime business partner.
“It was very, very popular and sort of opened people’s eyes to what could be done with a documentary,” Noxon said.”It was groundbreaking for its time.”
The rising popularity of documentaries in the early 1960s “was simply a question of television catching up with the public,” Rosten told The Times in 1963 as he cited the popularity of nonfiction books and magazines.
In the 1960s, Rosten worked for David L. Wolper, a major independent producer of documentaries, and made a number of National Geographic specials. They included an early Jacques Cousteau documentary and another about the grizzly bear.
When “Grizzly” was nominated for an Emmy, Rosten’s friends and colleagues placed an ad in Variety that his family said included this disclaimer: “This space paid for by the admirers of Irwin Rosten, a modest man who cannot be trusted to blow his own horn.”
He was born in 1924 in Brooklyn to immigrants from Russia and Poland who owned a drugstore.
After working for the DuMont Network in New York, Rosten moved to Los Angeles in 1954 and joined CBS affiliate KNXT. One of his highly regarded projects was “Thou Shalt Not Kill,” a 1958 documentary that examined capital punishment.
Writing in 1959, The Times’ Cecil Smith described Rosten as a “young man with magic in his pen.”
Two years later, he moved to KTLA-TV Channel 5 to become a writer-producer of documentaries and special programs. One of his final documentaries for the station was 1963’s “Split Image,” which was about Camarillo State Hospital’s patient-operated closed-circuit TV.
While working for Wolper, Rosten met Noxon, and the pair eventually jumped to MGM and set up the studio’s documentary unit. Their first venture was a 1968 documentary on Clark Gable.
As early as 1963, The Times referred to Rosten and Noxon as “one of the finest young teams of documentary makers.”
Rosten was known for mentoring others and was a terrific cook — Chinese food was a specialty, said his son, Peter, a former movie and TV producer.
The elder Rosten traveled the world in pursuit of his subjects, going to Japan to film parts of the 1970s National Geographic specials “Gold” or to Russia to record “The Volga” about the major European river.
As was often the case, Rosten returned with a story that amused him. A Soviet news agency official had proposed arm-wrestling to decide whether a Soviet or American film crew would be used on “The Volga.” Rosten’s heftier National Geographic colleague took the challenge, but the match ended in a draw. Crews from each country were used.
