No one played supercilious, judgmental mothers-in-law with as much enthusiasm as Mabel Albertson. The sister of comic actor Jack Albertson, Albertson made a few tentative stabs at a film career in the 1920s and 1930s, but chose instead to concentrate on stage work. Returning to Hollywood in 1953, she became a semi-regular on several television series, and also contributed sharply honed character performances in films like Home Before Dark (1958) (as Jean Simmons' disastrously well-meaning stepmother) and The Gazebo (1959) (as a garrulous real estate agent). She hit her stride in the 1960s playing the self-pitying mother and mother-in-law of such TV actors as Tom Ewell, Dick Van Dyke, and Bewitched's Dick York and Dick Sargent. Though the roles may have been stereotyped, she always managed to make them hilariously -- and sometimes disturbingly -- real. Mabel Albertson died of Alzheimer's disease at the age of 81.
