Okay, I hope we are talking about the same guy. This is what I come up with in my search.
Berek Latarus.
Born- Poland, Lodz. 1911. June 24.
mother was born in Czechoslovakia / father was born in Minsk.
father was in the lumber business and mother’s father was a tailor.
Experienced anti-semitism at early age, "Here’s the Jews coming,” and they used to chase us around. But as young people, you are not too much afraid. It was before the war --quite a few years before. "
All his relatives went to a concentration camp, "They all went to the concentration camp -- to Auschwitz in that time -- a very large family."
He was the only one to survive in his family.
Arriving in Auschwitz- "Well, we left in August in 1944. I would say by the end of August we were in Auschwitz. I don’t remember the day arriving -- who knew at the time what date."
On the Box car-
It was very crowded! There was, I think, a steel floor. It’s like a cattle boxcar, I would say, because there was some straw scattered around in the car. And later, we ourselves opened a little window on top next to the roof. We opened a window over there and there was some bars, but that’s all.
Greta, this is all from an interview I found in some history notes I have.
