Artist Hugh Merrill, who is white, had troubling memories from what he saw growing up in the Jim Crow South of the 1950s and '60s. And when he started looking into his family history, he was shocked by what he found out.
"It's a little bit like finding out that not only, if you were German, that your ancestors, that your uncles, were guards at Auschwitz — it's like finding out they ran Auschwitz," he says. "I had to make a decision about what to do with this. And it was absolutely clear what had to be done. I had to tell the truth."
