In 1998 a TV documentary called: Witness: Owning Auschwitz was produced by Granada TV in the UK telling the story of Mrs. Frank and her family's ownership of land at Auschwitz concentration camp; a book Owning Auschwitz was also produced by Mrs. Frank.
Just a few hundred meters from the gates of Auschwitz I is a piece of land owned by a Holocaust survivor, Mrs. Zypora Frank. Mrs. Frank inherited the land via her late grandfather, Jozef Melzer. In the 1930s, Jozef, a prosperous Polish Jewish businessman, built a factory that produced tar roof tiles on the land at Oświęcim, he also built a railway line to the tile factory.
The Germans confiscated the Melzer land and tore down Jozef's roof tile factory to build a new factory on part of the site and that German factory building, though derelict, still stands on the site today!
Jozef Melzer, along with many other members of Zypora's family, perished in the Holocaust, some of them at Auschwitz. But the young Zypora and her mother, father, and brother managed to flee east to escape the German invasion from the west, however the Soviets invading Poland from the east, rounded them up, and transported them to a gulag in Siberia. Ironically, this twist of fate probably saved their lives.
In doing some research on the Melzer land I recently discovered that the iconic photo of Auschwitz prisoners slaving away building the Krupps factory is actually the factory that was built on Jozef Melzer's land. This has not been picked up before.
