George Izenour, began conceptualizinga lighting fi xture with remote control of the pan, tilt, focus, beamangle, and color. He was employed by the Federal Theatre Project workingrepertory theatre when he realized the fl exibility that such a system mightafford. But the complexity of the system and the available technology atthe time made it virtually impossible to realize his concept. (English)

But the potentiometersused in the feedback circuit lacked the precision to provide accuraterepeatability. (English)
