Mary Wickes (born Mary Isabella Wickenhauser; June 13, 1910 – October 22, 1995) was an American actress. She often played supporting roles as prim, professional women, secretaries, nurses, nuns, therapists, teachers and housekeepers, who made sarcastic quips when the leading characters fell short of her high standards. Wickes's first Broadway appearance was in Marc Connelly's The Farmer Takes a Wife in 1934 with Henry Fonda. She began acting in films in the late 1930s and became a member of the Orson Welles troupe on his radio drama The Mercury Theatre on the Air.
