Phyllis Cerf Wagner died at age 90 on Friday. She was married to Bennett Cerf 1940-71. After Bennett's death she married Robert Wagner, the ex-mayor of New York, who also pedeceased her. As well as the spousal connection Phyllis was a guest panelist on WML more than a few times, as well as a mystery guest (sometimes with other panelist's spouses) at least three times.
Beyond who she married the former Phyllis Fraser was a very active and interesting woman. And, as we seemingly were reminded at least once a year on the show, she was Ginger Rogers cousin.
There's a good obituary in the New York Times.
