Marie Mahder (December 13, 1920 – January 28, 2001), best known by her stage name Sally Mansfield, was an American television character actress; she also had a few small roles in feature films including one with Dean Martin and Jerry Lewis.
Born in Oak Park, Illinois, Mansfield was a moppet radio star in Chicago, Illinois. Her father gave her the nickname "Sally". As a youth she joined the Actors Company of Chicago and the Children's Summer Theatre and studied at the Sherwood Music School. Coming to New York City in 1945, she voiced several radio roles for commercials and on soap operas and dramas. As a chorine with the Don Arden Dancers, she performed in revues in New York and in Las Vegas.
Moving to Hollywood, Mansfield met up with a talent scout for Paramount Pictures while she was in the Geller Workshop. She landed a bit part in Forever Female (1953) as the secretary of Paul Douglas. She was a regular on the CBS Gunsmoke radio show in 1954.
Mansfield gained notoriety for modeling a sweater designed by Edith Head, which she wore when she entertained U.S. Army troops in Alaska and Japan. The sweater's back was padded with heat-producing chemicals, and this then-novel idea along with Mansfield's photo was widely syndicated. She modeled a two-piece bathing suit in Pose! The Picture Magazine, in March 1955.
