I remember Valerie's character as Rhoda on The Mary Tyler Moore Show. Mary Richards and Rhoda Morgenstern lived in a big Victorian house in Minneapolis. The house had been split into apartments and their landlord also lived in the house. Her name was Phyllis Lindstrom.
Rhoda and Phyllis both had spinoffs of the show and I watched both. In addition to the opening for The Mary Tyler Moore Show, the openings for Rhoda and Phyllis are still some of my favorites.
After Rhoda, Valerie Harper went on to at least one other television show and also starred onstage.
I'm very sad to learn that she is dealing with this illness and the outlook doesn't look good. I did find Ed Asner's comments in Daily News uplifting and it reminded me of what his character Lou Grant told Mary Richards one day, "You've got spunk!"
Valerie Harper has spunk and I hope it helps her with this fight.
