"She wrote her life, and she lived her poetry." Marcel Reich-Ranicki. Thirty-seven years after the death of the great poetess, the first annotated complete edition of her works and letters is being published. This edition makes the complete works and correspondence of the poet Mascha Kaléko accessible to a wide audience for the first time. The works published during her lifetime and in her estate are supplemented by newspaper publications and unpublished writings from her estate. Her letters impressively showcase the literary development of the author Mascha Kaléko, as well as the poet as a private person - as a wife, mother, and friend. Her regular intellectual exchange with fellow writers such as Ingeborg Drewitz, Hilde Domin, Hermann Kesten, Walter Mehring, Kurt Pinthus, and many others provides valuable insights into literary history.
