 Happy 50th birthday LED! On the 9th of October 1962 Holonyak, who was then a consulting scientist at General Electric, demonstrated the first practical, visible spectrum LED at the company’s advanced semiconductor laboratory in Syracuse, New York. This first III-V alloy PN junction design is the prototype for all high-brightness LEDs made today. Many of the researchers who studied under Holonyak have subsequently refined the technology, through improvements in crystal manufacturing techniques, to develop bright-light LEDs in every colour, including white. Even today, at 84, Holonyak can be found in his laboratory daily. He was invited to join the Illinois faculty in 1963 and has been given the esteemed title ‘The John Barden Endowed Chair in Electrical and Computer Engineering and Physics at Illinois.’ Holonyak has won mulitple awards including the Japan Prize 1995 and the US National Medal of Science. He is also a member of the National Inventors’ Hall of Fame. http://www.lighting.co.uk/news/ha...90.article Happiness and depression are both feelings, just like joy and anger. It's not feelings that give us problems. It's what we do with them that makes the difference.
