Grizzly Adams star Dan Haggerty died on Friday at the age of 73. Longtime friend and manager Terry Bomar confirmed his death.

“He had cancer and had been fighting since July, and he had a great Thanksgiving and a great Christmas, and he died with his kids around him and people who love him,” Bomar told Fox News.

According to a report from the L.A. Times, Dan Haggerty learned just this past summer that he had cancer of the spine.

Haggerty’s parents hoped he would become a priest, but instead he was a “wild child.” He went to work for a ranch in California that trained animals for the movies. He soon became an animal handler and a stuntman on the side.

These skills eventually led to Dan Haggerty becoming an actor. It was thanks to a colleague he met while filming a scene that had him chasing a tiger across a frozen lake, that Haggerty eventually landed the leading role in a made for TV movie called The Life and Times of Grizzly Adams.

That led to his role in the TV series, also called The Life and Times of Grizzly Adams.

Dan Haggerty was Grizzly Adams, and in later years he still relished the role. He occasionally shaved off his trademark bushy beard for charity.

Haggerty lived a rather colorful life. He was arrested for selling cocaine (the charges were thrown out after a while) and he survived two serious motorcycle crashes. His wife, Samantha Haggerty died in a 2008 motorcycle crash when her bike hit a deer.
