For Wolf, visiting the memorial was an emotional reunion, providing a chance to heal but also to connect with the fellow survivors who became his family.
"You talk about so many things," Wolf said. "'What did you do? What commander did you work? What block, what barrack?'"
It was also a time to put this all behind him and move forward, enjoying the freedom of a simple life.
"It's like I'm free," Wolf said. "I can do what I want. I can work where I want. It's open for me."
