I just saw that on the news. One of the greats - her Maude TV show in the 1970s brought so many aspects of modern life to the fore, both comic and dramatic.
I remember once seeing her do a walk-on role on All in the Family. She came to the front door of Archie's house, and when Edith brought her inside to see Archie, she looked at Archie and said:
"Well hello Archie - still fighting mental health I see."
What a talented actor.
