Young Łaja (or Lolya) Cederbaum attended 8-year Female Humanities High School of Fanny Posnerowa in Warsaw, and she belonged to a theatre club, where she sang songs to her own accompaniment.

[2][3]) By the 1920s, her singing (in Warsaw) attracted the attention of Qui Pro Quo cabaret director Jerzy Boczkowski [pl].

[citation needed] She refused to join the Yiddish Theater Union, calling their audition process "The Inquisition".

Her last acting role was in Ven di zun geyt oyf (Sunrise, When the Sun Rises) with Ludwig Satz and Edmund Zayenda in 1941.

She subsequently joined the American army and remarried a non-Jewish contractor named Leland Benton; they settled in Miami Springs, Florida.
