Who Was Werner Heisenberg ?

As a result of the recently increased public debate about the person and character of my father, stimulated by Michael Frayn's Tony Award winning Broadway play "Copenhagen", I decided to present some pertinent material that highlights his integrity and humanity. It may help anyone who is interested arrive at a better understanding of my father's thinking and actions, just as his own account in "Physics and Beyond" (Harper & Row 1971) [German title: "Der Teil und das Ganze"] and my mother's "Inner Exile - Recollections of a Life with Werner Heisenberg" (Birkhäuser 1984) have attempted. In making this other material available to an English speaking public, I am hoping to reach the curious and the skeptical reader alike. This web-site will be continuously expanded after its launch in December 2000.
