Grizzly Adams, a peaceful mountain man with a luxurious beard and a bear named Ben, was portrayed by Dan Haggerty in the 1974 film “The Life and Times of Grizzly Adams” and the NBC television series of the same name. Haggerty passed away on Friday in Burbank, California.

His friend and manager, Terry Bomar, informed him that the cause of death was cancer of the spine.

Mr. Haggerty was working in Hollywood as a stuntman and animal handler when he received a request from a producer to perform in some opening sequences that he was reshooting for a movie about a woodsman and his bear.

It told the story of a man from California who was wrongfully convicted of murder and fled to the woods, where he developed a relationship with the creatures around him and tamed an orphaned bear. The story was based on the novel “The Life and Times of Grizzly Adams,” which was written by Charles Sellier Jr.

Mr. Haggerty gave his consent, but only on the condition that he took on the entire film. A new version of the movie was produced for a cost of $165,000, and it ultimately made close to $30 million at the box office. After that, it was adapted for television, and in February of 1977, Mr. Haggerty returned to his eco-friendly role as a protector of the forests and a friend to the animals.

In his review of the first episode, which was published in The New York Times, John Leonard stated that “it lukewarms the heart.” Mad Jack (played by Denver Pyle) and Makuma, a well-respected aboriginal man played by Don Shanks, bring flour and advise to the log cabin where the man and the bear have taken refuge. As they exit the lodge, the man begins to trap fur, while the bear begins to wash his fur. In the meanwhile, there are raccoons, owls, deer, bunnies, hawks, badgers, and cougars, as well as a significant amount of experience with nature and a significant lump in the throat.
