Nick Holonyak Jr., an electrical engineer who became known as the godfather of the LED lighting that illuminates flat-screen TVs and laptop computers, and who also developed lasers that enabled DVD and CD players, bar code scanners and medical diagnostic devices, died on Sept. 18 in Urbana, Ill. He was 93.His death, at a nursing home, was announced by the University of Illinois Urbana-Champaign, his alma mater, where he taught from 1963 until he retired in 2013. The day after he died, the campus’s State Farm Center arena was bathed in red to commemorate his invention of the first visible light-emitting diode in 1962.Professor Holonyak (pronounced huh-LON-yak) was among the first scientists to predict that incandescent bulbs, which heat metal filaments to create energy, and fluorescent lamps, which use ionized gas, would eventually be replaced by LEDs, semiconductor chips the size of a grain of sand that emit photons of light when electric current is applied to them.Professor Holonyak
