When I took a train to Levittown, Pennsylvania in August of 2018, my plan was to interview David Wisnia, a Polish Jew who’d arrived in Ellis Island in 1949. By the time he was 15, David was an orphan, alone in the world, fleeing Nazis. By sixteen, he was a prisoner in Auschwitz, forced to carry corpses in the most notorious Nazi death camp. And suddenly at eighteen he was clad in full American uniform, an interpreter for the US army. On its own, David’s saga was incredible.
