After WWI and the Russian 1917 revolutions, Berlin emerged as one of the leading centers of Russian emigration. In 1922, Soviet Russia and the Weimar Republic extended mutual diplomatic recognition, paving the way for yet another wave of migration. This article suggests that while Russian/Soviet Jewish migrants played a key role in the transfer of ideas between the two countries in the early interwar era, they were simultaneously engaged in a search for new Jewish culture. Exploring the case of the artist El Lissitzky, illustrative for a cohort of Russian-born Jewish intellectuals who engaged in the transfer of ideas between the Soviet realm and the Weimar Republic in the 1920s, the article probes the social history of overlapping Russian-Jewish migrant circles in Weimar Berlin. A deeper exploration of the topic, still a desideratum, will forge a more nuanced understanding of the cultural transfer between the German, Jewish, and Soviet societies during the early interwar era.
