In 1944, a little more than 10 years after having emigrated from Nazi Germany, Einstein wrote the following address for a Quaker Organization

"One who has come to this country… should speak out freely on what he sees and feels, for by so doing he may perhaps prove himself useful.

In the Unites Sates everyone feels assured of his worth as an individual. No one humbles himself before another person or class…

There is however a somber point in the social outlook of Americans. Their sense of equality and human dignity is mainly limited to men of white skins. Even among these there are prejudices of which I as a Jew am clearly conscious; but they are unimportant in comparison with the attitudes of the "Whites" toward their fellow citizens of darker complexion.

The more I feel an American, the more this situation pains me. I can escape the feeling of complicity in it only by speaking out."
