Esther Frumkin was the pseudonym of the Jewish educator, writer, and socialist-turned-communist Malkah Lifchitz. Active in the Russian and later Soviet leftist political scene in the early twentieth century, Frumkin was an independent thinker and a unique woman in the Jewish labor movement. However, she drew criticism from both Jewish and Communist leaders and died in a Soviet detention camp in 1943.

Jewish women played leading roles in the formative years of the General Jewish Workers’ Bund, which was established in the Tsarist Empire in 1897, and initially participated in the movement in large numbers. However, the Bund had somewhat less success in mobilizing women in independent Poland between the two world wars than it had during the Tsarist era.
