Mindell ponders the orgin of cybernetics beyond Norbert Wiener's 1948 hypothesis. Mindell returns to the time between the World Wars, when four disparate computing research cultures thrived in the United States: the U.S. Navy, the Sperry Gyroscope Company, the Bell Telephone Laboratories, and Vannevar Bush's laboratory at MIT. In each culture, different technical problems, organizational imperatives, and working evironment existed, but they were all researching control, communications, and computing. When President Roosevelt synthesized the four engineering cultures into a representative government committee, they suffused engineering research with good principles and later made it possible for Norbert Wiener's 1948 formulation of cybernetics.
