Ze’ev Rosenkranz, senior editor and assistant director of the Einstein Papers Project at the California Institute of Technology, said: “I think a lot of comments strike us as pretty unpleasant – what he says about the Chinese in particular. They’re kind of in contrast to the public image of the great humanitarian icon. I think it’s quite a shock to read those and contrast them with his more public statements. They’re more off guard, he didn’t intend them for publication.”
