When I was a teenager, I traveled to Auschwitz on a Jewish summer program. Since I played the saxophone, I was asked to perform the song “Eli, Eli” for a memorial service. It is a popular Jewish song my father made me sing every night before bed but I knew nothing of its origin. My tutor told me as I walked to the stage that Hannah Senesh, who wrote the poem on which the song is based, was a Hungarian-born, Palestine-based paratrooper who died trying to rescue Hungarian Jews during the Holocaust.
