Ed Asner, Co-Star on "The Mary Tyler Moore Show"

Cloris Leachman, Co-Star on "The Marty Tyler Moore Show"

"My heart goes out to her husband, Robert — he was never more than a touch away from her. The picture that we all have of her, that's how she was— sweet, kind, so tender, so delicate. She was America's sweetheart."

Bob Newhart, Longtime Friend

"She cared a lot about actors. When we'd go to the commissary, it was like a dream. There was Ed Asner, Betty White and the guy from 'Hill St,' I think Mary protected the actors and insisted they be treated with respect. I don't know that that exists anymore. She loved to work, that was what she lived for"

Dick Cavett, "The Dick Cavett Show"

"I don't now anybody else in show business that everybody who worked with liked. Believe me, that's a big thing."

Carol Burnett

"She will be so missed. She was a pioneer on television and also one of the sweetest, nicest people I ever knew."

Robert Redford, Director of "Ordinary People"

"Mary's energy, spirit and talent created a new bright spot in the television landscape and she will be very much missed. The courage she displayed in taking on a role, darker than anything she had ever done, was brave and enormously powerful."

Carl Reiner, Producer and Creator of "The Dick Van Dyke Show" on Casting Mary

"She walked into the room and there was this beautiful, starry-eyed girl with beaitiful hair and legs. I asked her to read and she read the first line and I heard a ping in her voice and my hand became a claw ... I clawed the top of her head, took her down the hall and said 'Here, I found her!'" -- Carl Reiner on casting her on "The Dick Van Dyke Show."

Michael Keaton, Co-Star on "Mary" and "The Mary Tyler Moore" Hour

Donald Sutherland, Co-Star In "Ordinary People"

Timothy Hutton, Co-Star In "Ordinary People"

"I am deeply saddened by the news of Mary's passing. She was a truly amazing person, a great friend and an inspiration to all. I will always be grateful for her kindness and thankful beyond words for knowing her. She will be missed greatly."
