Alice Dorothy Margaret Frost[1] was born on August 1, 1910, in Minneapolis, Minnesota,[2] the youngest of four children.

[11] An item in a 1939 newspaper noted Frost's "art of mimicry," saying "Alice is known to her friends as 'the girl of a hundred voices'"[12]—a talent which originated from her childhood, when she heard ministers who visited her home "when they returned from their missions in far-off places like Siam, India or Japan... [T]he missionaries delighted in teaching the little girl their various Hindustani, Javanese or Far Eastern dialects.

She also was heard in Song of the Stranger,[28] The Shadow, Grand Central Station,[29] The Campbell Playhouse, What Would You Have Done,[30] On Broadway,[31] Famous Jury Trials,[32] Al Pearce and His Gang,[33] David Harum, Lorenzo Jones, Suspense,[2] Aunt Jenny's Real Life Stories,[34] The Fat Man, Romance,[20] The Big Story, Les Misérables,[19] The Mercury Theatre on the Air,[10] Mr. District Attorney,[35] Johnny Presents,[36] The FBI in Peace and War,[37] Don Ameche's True Life Stories,[38] and Columbia Workshop.

[42] She appeared on Broadway in Green Grow the Lilacs (1931), The Great Lover (1932), As Husbands Go (1933), It's a Wise Child (1933), the Mercury Theatre productions Caesar (1937–38) and The Shoemaker's Holiday (1938), A Roomful of Roses (1955),[43] and The Bad Seed (1955).

She appeared in two episodes of Hazel and also had the role of Miss Bickle in the unsold pilot of the comedy His Model Wife.

[50] In the 1960s, Frost appeared in two episodes of The Twilight Zone ("The Sixteen-Millimeter Shrine" S1 E4 and "It's a Good Life" S3 E8, as Aunt Amy).

She also found roles in the decade's popular Westerns, appearing on The Tall Man, The Virginian and in two episodes of both Bonanza and Wagon Train.

Frost's final television work included a 1978 visit to Fantasy Island and a 1979 episode of Buck Rogers in the 25th Century, her last role.
