Parsons holds the 1958 patent for numerical control and was the sole inductee, without his own chief engineer Frank Stulen, into the National Inventors Hall of Fame for the invention, yet the MIT Servomechanisms Laboratory transformed his original plunge-cutting concept into the three-axis continuous-path control and the programming language that made numerical control practical, and historians differ on how much of the credit belongs to Parsons alone.What would resolve this A detailed technical comparison of Parsons' original 1949 proposal against MIT's delivered 1952 servomechanism system, establishing how much of the patented invention originated with Parsons versus MIT's own engineers, would settle the credit question.OpenHistory of mechatronics and control engineeringJohn T.
