While I appreciate the courtesy of the organizers of this symposium in asking me to talk about Enrico Fermi, I am not altogether certain that I am the most appropriate person: there are others here in the audience who knew him much better and much longer than I did or who were associated with him in some of his more well known contributions. I am probably unique in that I was associated with him in the least known of his work; and that may be an advantage since I can reflect on Fermi's broader interest in physics and not only on those special aspects which have made him well known.
