John Mahoney, the Cantankerous Dad on 'Frasier,' Dies at 77

A former Midwestern medical-magazine editor who quit his day job at nearly 40 to study acting in Chicago, Mahoney had taught English at Western Illinois University in the early 1970s.

He became a fixture at Chicago's fabled Steppenwolf Theater and soon ventured to the New York stage. He distinguished himself in an off-Broadway production of Orphans, for which he received a Theatre World Award.

Mahoney won a Tony Award in 1986 for his performance in a revival of John Guare's The House of Blue Leaves. The production was videotaped for PBS' Theatre in America series.

In 2007, he was back on Broadway in a revival of Prelude to a Kiss.

In movies, Mahoney garnered recognition in Barry Levinson's Tin Men (1987), playing Richard Dreyfuss' business partner. The same year, he was memorable in Moonstruck as a depressed college professor who regularly had affairs with his students.John Mahoney, who was best known as Kelsey Grammer and David Hyde Pierce's irascible dad Martin Crane on Frasier, has died. He was 77.

Mahoney died Sunday in Chicago, publicist Paul Martino told The Hollywood Reporter.

As a curmudgeonly retired cop, Mahoney received two supporting actor Emmy nominations for his work on the 1993-2004 NBC hit.
