Ed Asner, who played opposite Moore on the groundbreaking 1970s sitcom, wrote on Twitter, “my heart goes out to you and your family. Know that I love you and believe in your strength.”
Hours later, he added, “A great lady I loved and owe so much to has left us. I will miss her. I will never be able to repay her for the blessings that she gave me.”
In the 1960s, Moore played a housewife on “The Dick Van Dyke Show,” and she would eventually go on to play more dramatic roles after her run on her own sitcom. She won a Tony and an Emmy for such roles, and received an Oscar nomination in 1980.
Moore played a spunky Minneapolis local news producer on her eponymous show, a beloved character embraced by the city in real life.
Moore’s costar Cloris Leachman, who played the Phyllis Lyndstrom, said in a statement to Vanity Fair, “the picture that we all have of her, that’s how she was—sweet, kind, so tender, so delicate. She was America’s sweetheart.
On social media, several notable figures shared what Moore meant to them, and their grief at her passing.
