George Secor (born November 8, 1943), a composer from Chicago, is the discoverer of miracle temperament and eponym of the secor.
Secor and Hermann Pedtke's Motorola Scalatron (1974) is a Bosanquet generalized keyboard featuring a multicolored arrangement of 240 tunable oval keys, about which Secor said: "There is not much point in using this alternative keyboard for systems below 31 tones in the octave." However, "even if it were completely impractical musically, it would make a wonderful prop for a futuristic movie." Though its synthesizer capacities may not reach performance level, according to Easley Blackwood, "It has rock-steady tuning capabilities; you can always count on it to be right."
