Aleksander Weintraub was Polish poet and writer, from a Jewish family from Lwów. In the 1930s he published in the Lwów magazine "Sygnaly" (Signals) and other leftist papers. He was closely associated with the Polish Communist Party. In 1935 he was an initiator of the formation, and later a member, of the Congress of Cultural Workers, associated with the party. For his communist activism he was arrested in 1937 and imprisoned for two years. After the Soviets occupied Lwów he became one of the leading members of the collaborationist newspaper "Czerwony Sztandar" (The Red Flag"), writing mostly on cultural matters. In 1943 he was murdered by the German Nazis, either in Lwów, or in the Belzec concentration camp.
