Erwin Farkas was imprisoned at Auschwitz III with his brother, he was only 15 years old. In 2016 I accompanied Erwin back to Poland for the first time in 71 years. Here he is outside of one of the factories (currently still in use) that made up Auschwitz III.
Both Erwin and his brother, Zoltan, survived the Holocaust, and currently reside in the US. Over the years I've known Erwin, he's become a dear friend.
