The actress who played Jerry's mom on "Seinfeld" has died. Just 5 days after her 93rd birthday, Liz passed away peacefully in her sleep. Liz played Helen for the entire run of the show. She is the only non-central character who played. Helen and her husband, Morty, lived in Florida. She played a very over-protective mom. Liz played the eccentric neighbor, Mrs. Ochmonek, on ALF. Liz was an accomplished Broadway actress, appearing in 12 productions on the Great White Way. She wrote a book about her affair with James Dean. The book will be turned into a film. Liz was a go-go dancer in the 50s and loved to sing and perform. Liz is survived by her family. She died at 93. I am sad.
