Biographical Note

John T. Parsons (1913-2007) was a manufacturer and inventor of numerical control, which is the application of computer technology to manufacturing processes.

Parsons produced bombs and land mines for U.S. government during World War II. He conceived a machine tool for automatically producing aircraft structural shapes from punch card/tape input (1946); executed a contract to produce the world's first numerical control milling machine (1949) and monitored design and completion of the machine (1950-1952). Parsons also originated an aircraft operation that became the world's largest designer, producer, and overhauler of helicopter rotor blades and built the first all-composite airplane for the Office of Naval Research. He created many other processes involving computer applications to manufacturing and received approximately fifty U.S. patents in the fields of numerical control, marine propellers, foundry systems, and data acquisition manufacturing methods.

Parsons served as president and owner of the Parsons Corporation of Traverse City, Michigan, Detroit, Michigan, and Stockton, California (1954-1968). He was then president and owner of the John T. Parsons Company, Traverse City, Michigan (1968-1986).

Among his numerous awards, Parsons was the first recipient of the Numerical Control Society's Joseph Marie Jacquard Award as the Father of Numerical Control (1968), a recipient of the Society of Manufacturing Engineers Engineering Citation as the person whose brilliant conceptualization of numerical control marked the beginning of the second industrial revolution (1975), recipient of the National Medal of Technology (1985), and recipient of the National Tooling and Machining Association's Distinguished Service Award (1987).

He died in Traverse City, Michigan at the age of 93.
