Many people know I’ve spent years traveling back and forth to Germany, learning more about my great-uncle Arthur Kahn. Arthur was the first Jew killed in the Holocaust—an extraordinarily strange and painful distinction. For a long time, I think I wanted to understand his place in history. But these last few months, I started to realize that what I was really longing for was him. Who was this person? Who had he wanted to be? For @theatlantic, I wrote about his story. And mine.
