In 1944, Gerron was coerced into directing a Nazi propaganda film intended to be viewed in "neutral" nations (in Switzerland, Sweden, and Ireland, for example) showing how "humane" conditions were at Theresienstadt. Once filming was finished, Gerron and members of the Jazz pianist Martin Roman's Ghetto Swingers were deported on the camp's final train transport to Auschwitz. Gerron and his wife were gassed immediately upon arrival, along with the film's entire performing entourage (except for Roman and guitarist Coco Schumann).The next day, Reichsführer SS Heinrich Himmler ordered the closure of the gas chambers.
