Who is the most famous Cambodian -American?

When I think Cambodian American my mind goes to Dith Pran, the guy that wrote The Killing Fields. He came to America as a journalist and his story is forever ingrained in my memory. I believe he ped away a few years back but that who who I think of when I think of a Cambodian American, because he got it, he got it and understood it and lived it and did his best to communicate that to others.
