Heinz von Foerster German spelling: He was twice a Guggenheim fellow —57 and —64 and also was a fellow of the American Association for the Advancement of Science He is well known for his Doomsday equation formula published in Science predicting future population growth. As a polymathhe wrote nearly two hundred professional papers, gaining renown in fields from computer science and artificial intelligence to epistemologyand researched high-speed electronics and electro-optics switching devices as a physicist, and in biophysicsthe study of memory and knowledge.

He worked on cognition based on neurophysiologymathematicsand philosophy and was called “one of the most consequential thinkers in the history of cybernetics “. FogelHeinz von Foerster was an architect of cybernetics and one of the members of the Macy conferences[4] eventually becoming editor of its early proceedings alongside Hans-Lukas Teuber and Margaret Mead.

He was the grandson of Austrian architect Emil Ritter von Foerster. He studied physics kudwig the Technical University of Vienna and at the University of Breslauwhere in he received a Ph.

He moved to the USA inand worked at the University of Illinois at Urbana—Champaignwhere he was a professor of electrical engineering from — He also was professor of biophysics — and Director of the Biological Computer Laboratory — Additionally, in —57 and —64 he was a Guggenheim Fellow and also President of the Wenner-Gren-Foundation for anthropological research from — Fogel and Margaret Meadamong many others.


He influenced generations of students as a teacher and inclusive, enthusiastic collaborator. He worked in the field of cybernetics and is known as the inventor of second-order cybernetics. With his students he developed many innovative devices, including ultra-high-frequency electronics [9]. He also worked on mathematical models of population dynamics and developed a general model now called the ” von Foerster equation “.

It relates that a population ages, and that fact is the only one that influences change in population density; the negative sign shows that time flows in just one direction, that there is no birth and the population is going to die out.

It is therefore a transport equation ; it can be solved using a characteristics method. In he formed the Biological Computer Labstudying similarities in cybernetic systems in biology and electronics.

He was the youngest member of the core group of the Macy conferences on Cybernetics and editor of the five volumes of Cybernetics —a series of conference transcripts that represent important foundational conversations in the field.

It was von Foerster who suggested that Wiener’s coinage ” Cybernetics ” be applied to this conference series, which had previously been called “Circular Causal and Feedback Mechanisms in Biological and Social Systems”. A issue of Science magazine included an article by von Foerster and his colleagues P. Amiot proposing a formula representing a best fit to available historical data on world population; the authors then predicted future population growth on the basis of this formula.

Based on population data obtained from various sources, von Foerster and his students concluded that world population growth over the centuries was faster than an exponential. In such a situation, doubling-time decreases over time. Von Foerster’s tongue-in-cheek prediction of Doomsday on November 13,was based on an extrapolation into the future of doubling-time, with the finding that doubling-time would decrease to zero on that date. Responders to his Doomsday prediction objected on the grounds of the finite human gestation time of 9 months, and the transparent fact that biological systems rarely persist in exponential growth for any substantial length of time.


Those who knew von Foerster could see in his rejoinders an evident sense of humor. The hyperbolic growth of the world population observed until the s has recently been correlated to a non-linear second order positive feedback between demographic growth and technological development that can be spelled out as follows: Von Foerster authored more than publications.
