Abraham "Abe" Ellstein (Yiddish: אַבֿרהם עלשטײן, Avrom Elshtayn, July 7, 1907 – March 22, 1963) was an American composer, bandleader and recording artist in the Yiddish theatre and Yiddish popular music milieu. Along with Sholom Secunda, Joseph Rumshinsky, and Alexander Olshanetsky, Ellstein was one of the "big four" composers of his era in New York City's Yiddish Theater District scene.[1] His musical Yidl Mitn Fidl became one of the greatest hits of Yiddish-language cinema.
