PERSON
Julian Bigelow
American engineer (1913–2003) who partnered with Wiener on the wartime anti-aircraft fire control problem, co-authored the 1943 paper that founded cybernetics, and later served as chief engineer for John von Neumann's IAS computer at Princeton.
Julian Bigelow is the least famous of the three founders of cybernetics, and the one whose practical engineering skill made the theoretical breakthroughs possible. Trained as an engineer at MIT, Bigelow joined Wiener's anti-aircraft fire control project at MIT in 1940 as the man who would actually build what Wiener proposed mathematically. The partnership was productive across almost every dimension of the emerging field: the feedback predictor that became the proof-of-concept for cybernetic theory was Bigelow's engineering as much as Wiener's mathematics; the 1943 paper 'Behavior, Purpose, and Teleology' lists Bigelow as co-author with Arturo Rosenblueth and Wiener; and Bigelow's subsequent career as chief engineer of the Institute for Advanced Study's pioneering computer under John von Neumann made him a bridge between cybernetics and early computing.

Bigelow's role in the anti-aircraft project was to translate Wiener's mathematical predictor into working hardware. This was not straightforward. Wiener's equations described an ideal predictor;
