Booker T. Washington, the first Negro to appear on an American stamp. I remember that after placing the Booker T. Washington in my album and showing my mother how it completed the set of five, I had asked her, “Do you think there’ll ever be a Jew on a stamp?” and she replied, “Probably—someday, yes. I hope so, anyway.” In fact, another twenty-six years had to pass, and it took Einstein to do it.
