Dr. Lilith Sternin Crane is the ex-wife of Dr. Frasier Crane, and the mother and primary caregiver of Frederick Crane. She appears on the sitcoms Cheers and Frasier. She is Jewish, and shares the name with a demon goddess. She has a mother, Betty Sternin, who appeared on Cheers, played by Marilyn Cooper. She also has a half-brother, named Blaine, played by Michael Keaton. A running gag is that she is a very cold person (Martin once calls her "Frosty the Snow-wife"), though when she gets emotional, it's usually in abundance. She also has very pale skin, which is also the subject of several jokes. People also make jokes describing her as a witch or demon (in season 2, Martin says the signs of Lilith's presence on an island are "the sea starting to churn and all the birds taking flight from the trees"). She is a strict mother and does not let Frederick do many things his friends enjoy (her reaction to him turning goth is never seen, though she didn't inform Frasier of it in advance when Frederick visited him). She first appears on Frasier to reunite with her ex-husband, hoping they can find love again. She appears in the second season by chance, and goes to Seattle to tell Frasier she is getting remarried. After her husband leaves her for a man, she is so desperate she ends up sleeping with Niles. She later returns to seek sperm from Frasier, hoping to mother a sibling for Frederick. However, they call it off. She later encounters a man on a plane (played by Brent Spiner), with whom a romance is implied. Her final appearance is the Frasier episode "Guns and Neuroses", where she says goodbye to Frasier. She also had a guest appearance on the show Wings, and appeared alongside Frasier. She was played by Bebe Neuwirth.
