He comes from a family of Czech and Moravian Sinti. His father Antonín Hauer lost his first family, his wife, Rozalia Burian, and four children, Mary, Wilhelm, Matthew and Bert, in the Nazi concentration camps, and he was also imprisoned. Jan Hauer’s mother Božena Pflegerová survived the so-called Gypsy camp in Lety u Písku. Her three-month-old daughter Štěpánka died in the camp. Twenty years after the war, Jan Hauer, along with his father, was involved in seeking out information about the fates of his relatives he had never known. He still collects family photographs and historical documents. Thanks to him, in 2018, the researchers received a copy of several versions of the unfinished manuscript of his mother Božena Pflegerová Return unwanted, in the late 80s of the 20th century. She tried to cope with the horrific experiences of the imprisonment at Lety u Písku and intended to testify about these events to the public. In the long term, he cares not only for the memory of his family and the community of Sinti living in the Czech Republic, but he also fought for the removal of the pig farm in Lety and for public remembrance of the Roma victims of the Holocaust.

However, as Mr. Hauer writes in the book when remembering his relatives:  “If God grants it, we will meet again one day around a shared repast.” Mu delu tumengi Devlu ruva.
