HEINZ VON FOERSTER Heinz Von Foerster, A Second Order Cybernetician Stuart A. Umpleby The George Washington University Washington, DC 20052 lt is a pleasure to introduce this issue of Cyber 1949. ln those days of rejuvenation, he returned to netics Forum dedicated to my triend and mentor, the old riddle of the nature of the observer. With Heinz Von Foerster. As the following articles demon the encouragement of the psychiatrists Victor Frank! strate, Heinz is a man who inspires not only and Otto Potzl, he published a short monograph on admiration and respect for his scientific contribu a quantum mechanical theory of physiological tions but also great affection. He is an outstanding memory. During a visit to the United States he met human being as weil as a great scientist. The Warren McCulloch who not only had the data for his articles by Stafford Beer, Gordon Pask, Humberto theory of memory but who also introduced him to Maturana, Lars Lofgren, Edwin Schlossberg and the campus at urbana. Kenneth Wilson often recount personal experiences Through McCulloch, at conferences about Cyber· with Heinz. Kenneth Wilson provides a very useful netics: Circular Causa! and Feedback Mechanisms in overview of Heinz' major articles as weil as the work Biological and Social Systems sponsored by the of visiting cyberneticians in the Biological Computer Josiah Macy Jr. Foundation, he met the people who Laboratory. laid the conceptual foundation for understanding the I shall provide some background on how Heinz really complicated systems-teleological systems came to the University of lllinois, a briet discussion and self-organizing systems. The people attending of the effect that the Biological Computer Labaratory these conferences included Gregory Bateson, Julian had on the students who worked there, and finally Bigelow, Margaret Mead, John Von Neumann, some personal reflections on the importance of Norbert Wiener and Ross Ashby. Heinz was so fas Heinz' work for cybernetics, science, and society. cinated by the ideas that emerged at these meetings that after seven years of research at the University of lllinois in microwave tubes and ultra-highspeed oscillography, he went on sabbatical leave to learn The Years Before lllinois more about the neurophysiology of his enigmatic observer. After one year under the tutelage of Heinz has been a central figure in the field of Warren McCulloch at MIT and Arturo Rosenblueth in cybernetics since its beginning. During his student Mexico 'he returned to the University of lllinois and days he became involved with the Vienna Circle, a established the Biological Computer Labaratory to group of philosophers that included Wittgenstein, study computational principles in living organisms.(1) Schlick, Menger and Carnap. From them he devel oped an interest in the fundamental difference between the world as it is and its symbolic repre The Biological Computer Labaratory sentation in language or equati0ns. He wanted to Almost from the beginning it was apparent that learn more about the observer. However, the war the Biological Computer Labaratory (BCL) was not intervened and he spent those years in various labo an ordinary university research group. One of the ratories in Germany working on plasma physics and most amusing episodes in the history of BCL was microwave electronics. Luckily he survived the war the series of events that led up to Heinz's being unscathed in mind or body. After the war he helped mentioned in the cartoon strip Pogo, a distinction set up the first post-war radio station in Vienna and for scientists even rarer than the Nobel Prize.

The those whose elements interact and those with idea that the human population could through com elements that do not interact. He figured that data munication form a coalition and engage in a game on human population growth would be the most against nature was a particularly troubling idea. One complete set of data for a population with elements demographer called attention to the widely accepted capable of communication. The result was an article view that industrialization reduces rather than in Science in 1960 by Heinz Von Foerster, Patricia increases population. Heinz and his colleagues Mora and Lawrence Amiot called "Doomsday: Friday, pointed out that if an inverse relationship between 13 November, A.D. 2026."(2) They found that the population and technological know-how is applied to equation which best fit the data was not an expo the human population over the last couple of mil nential but rather a hyperbolic equation. There is a lennia then either Stone Age man was a technologi major difference. lf population is an exponential cal wizard who carefully removed his technological function of time, population will become very !arge achievements so as not to upset his inferior progeny as time increases, but within limited time the popu or our population has dwindled from a once astro lation will remain finite.
