Arnold Meyer Spielberg (February 6, 1917 – August 25, 2020) was an American electrical engineer instrumental in contributions "to real-time data acquisition and recording that significantly contributed to the definition of modern feedback and control processes". For General Electric he designed, with his colleague Charles Propster, the GE-225 in 1959. He cited the first computer-controlled "point of sale" cash register as his greatest contribution. His children include filmmaker Steven Spielberg, and screenwriter Anne Spielberg.
