Mary Wickes (June 13, 1910 – October 22, 1995) was one of Hollywood’s most unmistakable and beloved character actresses, a master of the deadpan delivery and the perfectly timed sarcastic quip. She carved a unique and memorable niche on stage, screen, and television playing a gallery of formidable, no-nonsense professional women—nurses, housekeepers, teachers, and nuns—who were perpetually unimpressed by the antics of the main characters. Her classic portrayals range from the acerbic housekeeper in The Man Who Came to Dinner and the stern nurse in White Christmas to the comically gruff Sister Mary Lazarus in the Sister Act films. With her sharp wit and hilariously high standards, Wickes left an enduring legacy as a quintessential scene-stealer.
