LOS ANGELES -- Ed Asner, the burly and prolific character actor who became a star in middle age as the gruff but lovable newsman Lou Grant, first in the hit comedy "The Mary Tyler Moore Show" and later in the drama "Lou Grant," died Sunday. He was 91.

Asner's representative confirmed the actor's death in an email to The Associated Press. Asner's official Twitter account included a note from his children: "We are sorry to say that our beloved patriarch passed away this morning peacefully. Words cannot express the sadness we feel. With a kiss on your head- Goodnight dad. We love you."
