A lyric poet and essayist of Jewish origin, Mieczysław Jastrun (1903-1983) is considered to be one of the most important Polish poets in Poland to come out of the period between the two world wars. During his lifetime, he published a dozen volumes of poetry and translated French, Russian, and German poets (including Rilke) into Polish. His lyric poems investigate the subjects of philosophy and morality against the dark backdrop of the Holocaust and the wartime and post wartime occupation of Poland. Czesław Miłosz included Jastrun in his very important and influential anthology, Postwar Polish Poetry.
