Raymond C. Goertz (March 12, 1915 - June 4, 1970) was an American mechanical engineer and an early pioneer in the field of robotics, specifically remote-controlled robots (see telepresence). In 1949, while working for the Atomic Energy Commission at Argonne National Laboratory, Goertz filed a patent for an early master-slave manipulator (U.S. Patent 2,632,574) in order to handle radioactive material. Goertz recognized the value of electrically coupling manipulators and laid the foundations of modern tele-robotics and bilateral force-reflecting positional servos.
