Actress Mary Field kept her private life such a well-guarded secret that not even her most devoted fans (including several film historians who've attempted to write biographies of the actress) have ever been able to find out anything about her background. So far as anyone can ascertain, she entered films around 1937; her first important assignment was the dual role of the mothers of the title characters in The Prince and the Pauper (1937). Viewers may not know the name but they have seen the face: too thin and sharp-featured to be beautiful, too soft and kindly to be regarded as homely. Mary Field is the actress who played Huntz Hall's sister in the 1941 Universal serial Sea Raiders; the spinsterish sponsor of Danny Kaye's doctoral thesis in A Song of Born (1947); the nice lady standing in Macy's "Santa Claus" line with the little Dutch girl in Miracle on 34th Street (1947); the long-suffering music teacher in Cheaper by the Dozen (1950); and Harold Peary's bespectacled vis-a-vis in The Great Gildersleeve (1942)--to name just four films among hundreds.
