> Heinz von Foerster (née von Förster; November 13, 1911 – October 2, 2002) was an Austrian-American scientist combining physics and philosophy, and widely attributed as the originator of second-order cybernetics. He was twice a Guggenheim fellow (1956–57 and 1963–64) and also was a fellow of the American Association for the Advancement of Science, 1980.

## Summary
Heinz von Foerster (1911–2002) was an Austrian-American scientist who combined [[Physics|physics]] and philosophy to develop the field of [[Second-order_cybernetics|second-order cybernetics]]—an extension of classical [[Cybernetics|cybernetics]] that includes the observer as part of the system being observed. A Guggenheim fellow and fellow of the American Association for the Advancement of [[Science]], von Foerster published the influential 1960 "Doomsday equation" in *Science*, a [[Mathematical_model|mathematical model]] of human population growth that revealed exponential dynamics in social systems. His theoretical contributions revolutionized cybernetics by introducing the principle that any system sufficiently complex to observe itself becomes circular and reflexive, fundamentally changing how we understand [[Feedback|feedback]], [[Information|information]], and the relationship between observer and observed. Von Foerster's work bridges [[Engineering|engineering]], mathematics, and philosophy in a unified vision of self-organizing systems.
## Key points
- Originator of second-order cybernetics, including the observer in system analysis
- Published the Doomsday equation modeling exponential human population growth
- Guggenheim fellow and AAAS fellow
- Demonstrated reflexivity and circular causality in complex systems
- Bridged physics, philosophy, and engineering in [[Systems_theory|systems theory]]
## Relation to System
Von Foerster's second-order cybernetics fundamentally reframes systems theory by recognizing that observers of systems are themselves part of those systems. This insight has profound implications for how we understand feedback, control, knowledge, and the nature of complex self-organizing systems.
