Bill Moog
William Moog (August 15, 1915–1997) is known for inventing the electrohydraulic servo valve in 1951. He founded Moog Inc., which makes actuators for aircraft. He was born in New Jersey. His cousin was Robert Moog Robert Arthur Moog ( ; May 23, 1934 – August 21, 2005) was an American engineer and electronic music pioneer.

Electrohydraulic Servo Valve
An electrohydraulic servo valve (EHSV) is an electrically-operated valve that controls how hydraulic fluid is sent to an actuator.https://www.moog.com/literature/ICD/Valves-Introduction.pdf Servo valves are often used to control powerful hydraulic cylinders with a very small electrical signal. Servo valves can provide precise control of position, velocity, pressure, and force with good post-movement damping characteristics. History of electrohydraulic servo valves The electrohydraulic servo valve first appeared in World War II. The EHSVs in use during the 1940s was characterized by poor accuracy and slow response times due to the inability to rapidly convert electrical signals into hydraulic flows. The first two-stage servo valve used a solenoid to actuate a first stage spool which in turn drove a rotating main stage. The servo valves of the World War II-era were similar to this — using a solenoid to drive a spool valve. Advancement of EHSVs took off in the 1950s, largely due to ...

Robert Moog
Robert Arthur Moog ( ; May 23, 1934 – August 21, 2005) was an American engineer and electronic music pioneer. He was the founder of the synthesizer manufacturer Moog Music and the inventor of the first commercial synthesizer, the Moog synthesizer, which debuted in 1964. In 1970, Moog released a more portable model, the Minimoog, described as the most famous and influential synthesizer in history. Among Moog's honors are a Technical Grammy Award, received in 2002, and an induction into the National Inventors Hall of Fame. By 1963, Moog had been designing and selling theremins for several years, while working towards a PhD in engineering physics at Cornell University. He developed his synthesizer in response to demand for more practical and affordable electronic music equipment, guided by suggestions and requests from composers. Moog's principal innovation was the voltage-controlled oscillator, which uses voltage to control pitch. He also introduced fundamental synthesizer conce ...

Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...
