This special occasion, I realize, calls for a special selection among the many remarkable instances which the name of Niels Bohr brings back to my mind. It seemed indicated, at first, that I should restrict my account to those reminiscences which bear directly upon specific topics in physics and to omit others of more general human interest. But as I thought more about this talk, I realized that such an omission would present a grossly distorted picture, and that an essential feature of Bohr's character would be lost if one tried to distinguish between the professional and the personal manifestations of his great personality.
