Woodward, Inc. is the worlds oldest and largest independent designer, manufacturer, and service provider of control systems and control system components (e.g. fuel pumps, engine controls, actuators, air valves, fuel nozzles, and electronics) for aircraft engines, industrial engines and turbines, power generation and mobile industrial equipment. Woodward, Inc. was founded as The Woodward Governor Company by Amos Woodward in 1870. Woodward Governor Company initially made controls for waterwheels (first patent No. 103,813) and then moved to hydro turbines. In the 1920s and 1930s Woodward began designing controls for diesel and other reciprocating engines and for industrial turbines. Also in the 1930s, Woodward developed a governor for variable-pitch aircraft propellers. And when the United States militarys first turbine-powered aircraft successfully flew, its GE engine had a Woodward control. Starting in the 1950s, Woodward began designing electronic controls, first analog and then digital units.
