I like this story about Einstein:
The world, or rather a highly exclusive part of it, had to come to Einstein if it wanted an audience. And come it did. The most famous names of the era, like Max Planck, Rabindranath Tagore, Heinrich Mann, Chaim Weizmann and Käthe Kollwitz, made the pilgrimage to Caputh to see Einstein, and some were shocked to find him warmly greeting them barefoot and in his sailing shirt. (When Elsa Einstein complained about his informality, Einstein said, "If they want to see me, here I am. If they want to see my clothes, they can look in my closet.")
