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.
Also, the correspondence between my parents (1937-1946) have been published: "My Dear Li", Yale University Press, 2016.
Furthermore, Werner Heisenberg's 1941 Essay "Ordnung der Wirklichkeit" has been translated and is supposed to be available with comments by E.P.Fischer soon under the title:"Reality and its Order" by Springer. 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 from time to time be expanded after its launch in December 2000.
