Alan Thicke died Tuesday at the age of 69 after he reportedly had a heart attack while playing hockey with his son. 

Thicke, best known for his role as the patriarch on the sitcom Growing Pains along with his onscreen son Kirk Cameron, and most recently appeared on Netflix’s Fuller House, also hosted a successful daytime talk show in Canada and launched the syndicated Thicke of the Night in 1983. 

Brad Schwartz, president of Pop TV, the home of his unscripted show Unusually Thicke, told THR: “We are deeply saddened to hear of Alan’s passing. He was a part of our Pop family and was a tremendous talent. He was also for all who knew him, an amazing father and a true gentleman. We had the privilege to work with America’s Favorite Dad and his loss is one that is deeply felt.”

Thicke’s son Robin called his dad, “the greatest man I ever met,” in a conversation with the L.A. Times, adding that the elder Thicke was “always a gentleman.” Robin Thicke added that one of the last things said by his father, who died while playing hockey with his son Carter, was a compliment to Carter on a nice shot.

“The good thing was that he was beloved and he had closure,” Robin Thicke added. “I saw him a few days ago and told him how much I loved and respected him.” The younger Thicke also posted a version of that statement to his Instagram account.

Alan Thicke’s TV son on Growing Pains, Cameron, posted a statement to his Instagram and Facebook accounts, reading in part: “I spent Monday through Friday for seven important years with Alan Thicke as my ‘TV dad’ … I am so blessed to have grown up with him. [My wife] Chelsea and I send our love and prayers to his family tonight. We will cherish the memories … ‘sharing the laughter and love.'”

TV legend Norman Lear remembered his friend and colleague: “Alan and I had a part to play in one another’s lives. It was the happiest of relationships. We worked together on Fernwood 2Night. And while I was the producer, he was as much, or more, the show’s heart and soul as I might have been. Alan had as fine an understanding of the ridiculousness of the human condition as anybody. And that’s what the show was about – they were a pair of media fools. Who knew we would go on to have generations of them?” 

Leonardo DiCaprio, who appeared on the final season of Growing Pains, also posted a tribute to Alan Thicke on his Facebook page. DiCaprio wrote, “Alan was a devoted father, husband, friend and role model. He knew how to harness the power of the entertainment industry to be a positive influence in so many lives — including mine. I will be forever grateful for the opportunity I had to work with Alan early in my career. He had tremendous class, a huge heart, and he taught me and so many others the valuable lessons about humility and gratitude. I’ve seen him a number of times over the years and when Alan Thicke walked in the room, quite frankly, no one was cooler. I miss him already — my thoughts and prayers are with the entire Thicke family during this difficult time.”

ABC’s 1980s-set comedy The Goldbergs paid tribute to the late actor on Wednesday’s episode, with a brief slate before the episode began. 

Fellow Growing Pains co-star Tracey Gold also remembered Alan Thicke on Twitter.

After hearing the news on Tuesday, several friends and colleagues paid tribute online.
