RIP Nick Holonyak Jr

It's a good thing I was an engineer and not a chemist.  When I went to show them my LED, all the chemists at GE said, "You can't do that.  If you were a chemist, you'd know that wouldn't work."  I said, "Well, I just did it, and see, it works!"

-- Nick Holonyak Jr. (3 November 3 1928 - 18 September 2022), American engineer and educator.  He is noted particularly for his 1962 invention of a light-emitting diode (LED) that emitted visible red light instead of infrared light while working at General Electric's research laboratory in Syracuse, New York.  After leaving General Electric in 1963, he returned to his alma mater, the University of Illinois at Urbana-Champaign, where he later became John Bardeen Endowed Chair Emeritus in Electrical and Computer Engineering and Physics, as quoted by the Illinois News Bureau, "Nick Holonyak Jr., pioneer of LED lighting, dies" (18 September 2022)
