Looks like she did mostly film and television. She’s 94.

“In addition to her film and television work, Cook appeared in the original Broadway productions of 42nd Street and Romantic Comedy and was the second actress (after Carol Channing) to star as Dolly Levi in Hello, Dolly! She played Mrs. Peacham in the 1956 off-Broadway production of The Three Penny Opera, starring Lotte Lenya.[citation needed]!”
And as with many in show business,...
“Cook is a longtime supporter of various AIDS organizations and regularly appears as a featured performer in the annual Los Angeles S.T.A.G.E. benefit. With her actor husband, Tom Troupe, Cook received the 2002 Theatre Ovation Award for Lifetime Career Achievement, the first husband and wife to be so honored. Cook received the Distinguished Alumni Award from Baylor University, the S.T.A.G.E. Producers Award and the Hero in the Fight Against AIDS Award from the Richmond/Ermet AIDS Foundation, as well as eight Drama-Logue and Robby Awards.[citation needed]”
Not sure that makes her a “Broadway Grand Dame”.
Like, for example - I saw Bernadette Peters’ opening night when she took over from Bette Midler in Hello Dolly this January.
When she sang “It’s so nice to be back home where I belong” it stopped the show for six and a half minutes.
THAT is what I would consider a B’way Grand Dame. Compared to that, Bette Midler is a lounge singer.
And this broad? It’s news to me she took over for Carol Channing. How long did she run?
