From a Washington Post story by Scott Allen headlined “Ernie Grunfeld’s son details his family’s journey from the Holocaust to the NBA in new book”:

During his junior year at Stanford, Dan Grunfeld wrote a 20-page family history for one of his American Studies classes, and it focused in part on his father, Ernie, the only NBA player whose parents survived the Holocaust. Grunfeld’s professor told him it was an amazing story, and while the leading scorer on the Cardinal’s 2004-05 men’s basketball team was more focused at the time on following in his dad’s footsteps and making it to the NBA, the positive feedback stuck.
