A hidden note by Franciszek Kempa, a Jewish prisoner at Dachau, reveals hope amidst horror. Kempa crafted a violin in 1941, which was later discovered by art dealers in Hungary. The note, found inside the violin, explains the challenges he faced while creating it. Kempa survived the war and returned to Poland, where he continued making instruments. The violin symbolizes resilience and hope, especially as the 80th anniversary of Dachau's liberation approaches.
