My wife's grandfather was imprisoned in Buchenwald for the crime of being a Czech man in the Sudetenland born in 1921. He survived because he was a master carpenter, and he was kept alive repairing and building furniture for the camp. He walked home to Czechoslovakia (at the time).

I've seen pictures of him after he returned home. A skeleton in a suit and hat. Very sobering photos.

I got to meet him a couple of times before he died. A very, very quiet man. He was back in his home with his carpentry shop built on the side. He lived there 60+ years after the war. I can only imagine the thoughts he must have had being back in "normal life" after years of watching unimaginable horrors.
