Nick Holonyak Jr. demonstrated the first practical visible-spectrum light-emitting diode at General Electric on October 9, 1962. His gallium arsenide phosphide device emitted visible red light, taking LED technology beyond the infrared devices that came before it. The experiment helped establish a field whose descendants now illuminate displays, homes, roads and vehicles.
Who was Nick Holonyak?
Holonyak was born on November 3, 1928, in Zeigler, Illinois, to an immigrant coal-mining family. Before college, he worked on the Illinois Central Railroad. He became the first member of his family to attend college and earned his bachelor’s degree in 1950, master’s degree in 1951 and doctorate in 1954, all in electrical engineering at the University of Illinois. John Bardeen, who later won two Nobel Prizes, was his first doctoral adviser.
After working at Bell Telephone Laboratories and serving in the U.S. Army Signal Corps, Holonyak joined General Electric’s Advanced Semiconductor Laboratory. He returned to the University of Illinois as a professor in 1963, where he continued research and mentored generations of engineers until retiring in 2013. The University of Illinois remembrance and the Holonyak Micro & Nanotechnology Lab biography document his career.
What did Holonyak invent?
On October 9, 1962, at GE, Holonyak demonstrated a light-emitting diode that produced visible red light. He used gallium arsenide phosphide crystals. Earlier LEDs emitted infrared radiation, which people cannot see; Holonyak’s device made semiconductor light visible to the human eye and practical as a visible source.

- Premium Quality: High-conductivity silver-plated pins and durable materials ensure long-lasting performance.
This was not the invention of electroluminescence itself, nor did Holonyak invent every later kind of LED. His achievement was the first practical visible-spectrum LED, a milestone that opened the way for visible LED indicators and displays and, through subsequent advances by many researchers, modern lighting. The University of Illinois News Bureau’s obituary reports the date and experiment.
The Grainger College of Engineering remembrance recounts a skeptical colleague saying, “You can’t do that,” and, “If you were a chemist, you’d know that wouldn’t work.” Holonyak replied, “well,” replied Holonyak, Jr., “I just did it, and see, it works!” The exchange captures the experimental confidence behind the demonstration.

How did his work shape technology beyond the red LED?
Holonyak’s influence extended across semiconductor devices and optoelectronics. His work included a shorted-emitter thyristor, a semiconductor switch used in household dimmers and power tools; visible laser diodes, used in phones and CD and DVD players; and quantum-well lasers, including the first demonstrated with his students in 1977. He also contributed to fiber-optic communications.
