John Mahoney has died.
The actor passed away on Sunday in Chicago, Illinois, his manager confirmed to PEOPLE. He was 77.
Born in Blackpool, England, in 1940, Mahoney became best known for his role as Martin Crane in NBC’s Frasier, though he didn’t kick-start his acting career until later on in life. As a child, Mahoney — who was one of eight children from a Irish-Catholic family — witnessed the struggles of war firsthand as it quickly tore apart his parents’ marriage.
He will be forever in our hearts.
REST IN PEACE.
