The Lemberg Mosaic, subtitled the "Memoirs of Two who Survived the Destruction of Jewish Galicia," is a book on the Holocaust by Jakob Weiss. This work brings to light the relatively obscure history of the systematic and total destruction of Jewish Lemberg (Lwów, now Lviv in Ukraine). It is presented in the format of a biography, detailing the struggle for survival of four families in the backdrop of two back-to-back invasions of the city and surrounding region by both the Soviets (1939) and the Germans (1941).
