Eva Justin was an assistant to Dr. Robert Ritter, the Third Reich's "expert" on Roma (Gypsies). She studied these Romani (Gypsy) children as part of her dissertation on the racial characteristics of Roma. The children stayed at St. Josefspflege, a Catholic children's home in Mulfingen, Germany. Justin completed her study shortly after this film was taken. The children were deported to Auschwitz-Birkenau, where most were killed.
