Jay Forrester

system dynamics founder; Industrial/Urban/World Dynamics.

Professor Emeritus at MIT's Sloan School of Management, Forrester pioneered system dynamics in the 1950s as a rigorous method for modelling complex feedback systems. His trilogy—Industrial Dynamics (1961), Urban Dynamics (1969), and World Dynamics (1971)—established the discipline and directly inspired The Limits to Growth report. He also invented magnetic-core memory, a foundational advance in early computing.
