Fredy Hirsch, a proud Jew and openly gay man, was born in Germany in 1916. When the anti-Semitic Nuremberg Laws were enacted in 1935, Hirsch fled from Germany to the Czech Republic, where he worked as a much admired sports teacher in a Jewish youth club. With the deportation of the Jews to Terezin — a combination of ghetto and concentration camp — Hirsch was appointed head of the Youth Services Department and helped care for more than 4,000 children and teens. Later, when he was sent to Auschwitz, Hirsch managed to persuade Josef Mengele to set up a daycare center, providing some 600 children their final moments of happiness. Ironically, it was in Auschwitz that Hirsch escaped homophobia for the first time in his life: He was out and had a lover, but people embraced Hirsch for his good work. Combining rare photographs, archival footage, witness testimony, and animation, “Dear Fredy” tells Hirsch’s amazing story, which includes planning a never-realized revolt with members of the underground in Auschwitz.
