John Mahoney, the veteran actor best know for playing the cantankerous father on the 90s NBC hit Frasier, has died at 77 on Sunday.
Mahoney’s longtime manager, Paul Martino, said Monday that Mahoney died in Chicago after a brief hospitalization.
The cause of death was not immediately announced.
The British-born actor starred as Martin Crane alongside his on-screen sons Kelsey Grammar, who played the titular Frasier, and David Hyde Pierce, who played Niles, in the sitcom for a whopping 11 seasons, from 1993 to 2004.
In 2000, he was awarded a SAG Award for his work on the show, and was also nominated for two Emmy Awards and two Golden Globes.
Besides starring in the hugely popular sitcom, John also had a lucrative film career, with roles in productions including The American President, Say Anything… and Eight Men Out.
Most recently, John had a recurring role in TV Land’s Hot In Cleveland, where he appeared as Roy in six episodes between 2011 and 2014.
His last TV appearance was in Foyle’s War in 2015, where he played Andrew Del Mar.
Aside from his careers in film and television, John was also active in theatre, and won a Tony in 1986.
John was intensely private about his personal life, but is thought to have never married, despite previously claiming to have been in several relationships.
