Jay Forrester is a professor and founder of the field of system dynamics.
Forrester directed the MIT Digital Computer Laboratory, which built whirlwind, the first digital computer, at MIT.
He invented random-access, coincident-current, magnetic memory which launched the era of reliable digital computers.
At the MIT Lincoln Laboratory, he directed development and installation of the SAGE system for North American air defense.
Forrester has pioneered the use of system dynamics in management education, applications to social systems, and more recently, system dynamics as a foundation for a more relevant pre-college education from kindergarten through 12th grade.
