US actor Finn, who was seen in popular TV shows like Friends, "Seinfeld" and The Middle, has died aged 60.
The comedic improv actor died at home in Los Angeles, California this Monday after undergoing treatment for a cancer diagnosis from 2022 onward, per reports.
"He saw everyone as a friend - solely future friends he hadn't encountered," his relatives said in a message.
They noted that he had "embraced life completely - with happiness and energy".
His initial on-screen part was on the George Wendt Show in 1995, where he appeared as the brother of the main character.
He was also seen in a regular part on Murphy Brown between 1995 and 1997.
He appeared as a party host named Joe Mayo in "Seinfeld" in the late 90s, playing a host famous for delegating burdensome jobs to his guests.
In the late 1990s and early 2000s, he made guest appearances on a variety of popular shows, such as:
He was most recognized for playing the character Bill Norwood in The Middle, starring in eight seasons of the show from 2011 to 2018.
His cinematic roles encompass It's Complicated (2009) and Santa Paws 2: The Santa Pups (2012).
Outside of his acting parts, Finn was deeply involved in improvisational comedy and worked as a teacher at the University of Colorado, where he was a professor.
He was involved with a six-member improv team called "Beer Shark Mice".
"Finn coached, befriended and mentored numerous pupils throughout the years and it's nearly impossible to find a person anywhere who has anything negative to say about him," his relatives stated.
Offering condolences, colleague and actor actor Richard Kind said there was "not a more kind, gentle, or funny, authentic human being you could encounter".
"Perpetually optimistic, making those around him better and funnier. A wonderful father and man," he shared on social media.
