The first LED was developed by Nick Holonyak Jr., often referred to as the “father of the LED”, working as a scientist for General Electric in 1962. His was a red LED—and the first LED that could be seen by the human eye, which later led to the accidental discovery of infrared diodes.
2014 Nobel Prize in Physics awarded to inventors of blue LEDs By David Szondy 10/7/14 The blue LED is the key to practical LED lighting. Invented in its practical form just 20 years ago, the blue LED is the long sought after “missing link" of lighting technology that made LED lamps possible, yet eluded scientists and engineers for 30 years.
