Alois Kreiner and his wife Josephine Kreiner hid the Czech Jew Ludwig Posiles from the Nazis during World War II. The couple owned a vinery where Posiles was working during the day. At night he stayed in the attic of Alois' and Josephine's apartment.
Kreiner told his customer that Posiles was a relative of his. Usually they believed Ludwig Posiles was an "Aryan". Still there was a high risk of the Gestapo setting its sights on them. The couple shared everything they had with Ludwig and even paid him for his work. Often they sent food to his brothers Walter and Hans who were hiding in other apartments. Ludwig Posiles stayed with them till the end of the war.
