Willie Garson's cause of death has been publicly confirmed.
The actor, who was best known for playing Carrie Bradshaw's sidekick, Stanford Blatch, in Sex and the City, died aged 57, per his son, Nathen Garson.
Garson - who was also known for his role as Mozzie on USA Network series White Collar - died from pancreatic cancer, his loved ones said in his obituary published in The New York Times on Thursday, September 23.
In the touching obituary, his family wrote that they always knew he was destined to act, adding that "nothing could better describe" the actor than the term "working actor."
"A working actor has been defined as 'an actor who while never achieving stardom, has a long and productive career and earns a better than decent living and has the admiration of his peers,'" the obituary reads.
"Nothing could better describe Garson. For the last four decades, he appeared in over 300 television shows and over 70 films."
In addition to his expansive filmography, Garson also acted in theater productions across the country, working with companies including Naked Angels, Manhattan Theatre Club, Roundabout Theatre Company, and the Geffen Playhouse.
"Garson was a ubiquitous presence in American pop culture," his loved ones wrote.
They continued: "He could be a classmate of Michael J. Fox on Family Ties or a waiter on a Cheers episode, or L. Harvey Oswald in an independent film Ruby or Bill Murray's assistant in Groundhog Day. He could just as easily be a TV executive in Soapdish as a man with mysterious luck in The X-Files as the president of an apartment board on Friends."
Garson's death was announced by his son, who took to Instagram to share touching images of his beloved father.
"I love you so much papa. Rest In Peace and I'm so glad you got to share all your adventures with me and were able to accomplish so much. I'm so proud of you. I will always love you, but I think it's time for you to go on an adventure of your own," his son Nathen wrote alongside the images.
"You'll always be with me. Love you more than you will ever know and I'm glad you can be at peace now. You always were the toughest and funniest and smartest person I've known. I'm glad you shared [your] love with me. I'll never forget it or lose it."
